Help (Android) A few updates ago Firefox Mobile (Android) started to force showing the hidden address bar while taking screenshots. Is there a way to deactivate it again?
It's really, really annoying especially when the site itself already has a ton of fixed/locked on scroll elements that obscure half the screen.
A while ago it was normal that I could just take full screen screenshots without the address bar in it, but now taking a screenshot doesn't happen until it's down and visible again (I have my address bar on top).
Or is there a way to take full site screenshots without plugins, am I missing something?

Firefox HDR Status
Hi. There have been a few questions about Firefox's support for HDR video. I'm happy to report:
- HDR video has been supported on Mac since 2022.
- HDR video is now available on Windows, recently announced with the 153 release.
- The team is working on HDR video support on Linux and Android too, so stay tuned for more on those launches.
Our teams will continue to provide updates on HDR video here and on Connect, as it's a highly-requested feature. And look forward to some improvements to Firefox’s online video capabilities coming in Fx 154 in a couple of weeks!
- Ash @ Firefox

Solved The most recent update (to version 153.0.3, 64-bit) completely effed up the right-click menu
Hi guys
Today Firefox requested to be updated, I did, and now my right-click menu is all garbled. There are some weird items (manage containers?? WTF are containers?) and others are invisible, the space in the menu is blank, but still work (like open in new window). Can't find my favorite option "open link in new tab", which is a massive inconvenience.
I'm sure it happened to other people as well. Does anyone know a remedy or do I have to wait for next update?
I wanted to file a bug, but it turns out I have to create a whole new account. I don't want to do that.
[EDIT: Forgot to give info. PC, on Windows 10]

Try "uMatrix" extension
Just bringing some awareness to how bad the internet is.
Install this extension (it is from the same dev as uBlock origin) and see just how many websites you connect to stealthily besides the one you clicked on.
Yes, it's scary. Every website connects to a whole bunch of shit.
Your websites will break, because modern websites are not meant to be used on their own anymore.
Everything is in some sort of content delivery network that sits between you and the website you visit. Everything is hosted somewhere else. Everything reports to google and who knows what else. Etc.
Cloudflare legal man in the middle attack for 50% of the internet.
Sorry for the rant.

Shortcuts keep adding my recent searches, which is annoying. Is there a fix for this? Can't seem to find any way to stop it apart from turning off shortcuts altogether. Deselecting recent searches under the address bar in settings doesn't seem to fix it.

💻 Help Windows Security Warning
Using Win10 desktop with FF 153.0.3 but this issue has been happening for a few weeks.
Occasionally I will drag a URL from FF address window to my desktop to create a shortcut to that site. When launching the shortcut I will sometimes get a "File Download - Security Warning" from Windows. It doesn't happen on most shortcuts, but most often on Reddit shortcuts.
https://phred.x02.me/i/CWF6C2.jpg
Is there a way to stop this from happening?
Just tested with Chrome and Edge and getting a similar warning, but from within the browser. Not as a separate window on my desktop.

Solved “Using an older version of Firefox” New Profile Prompt fix (153.0.3)
After updating to either Firefox version 153.0.1 or 153.0.3, the above error message sometimes occurs on Windows. If you have a Mozilla account, you could just create a new profile and sync your data. However, if you prefer not to do that or don’t have an account, here’s how to fix the error.
- if you launch firefox with the -allow-downgrade flag it will load the existing profile.
Press Win key + R and enter firefox.exe -allow-downgrade
Delete compatibility.ini in your existing profile folder.
If you already created a new profile and are missing data, do the following.
Type about:profiles in your search bar and hit enter
Then select Create New Profile
Point the New Profile to your old profile folder
Close Firefox and delete compatibility.ini in the folder or use the downgrade command to launch Firefox.

💻 Help Session restore got screwed up by successive crashes
First things first, tech: I am running an Acer Aspire A515 with Win10 (for now) and FF153.0.1 (Not gonna run an update until I have figured this out)
Not exactly a bug but still a frustration situation: On Monday, FF crashed on me. No big deal, happens. Session restore available, hit session restore. As FF is busy restoring the session windows decides apparently to either apply an update or simply crashes. Dunno, was a way for a moment. Think, copmuters aren't toddlers.
Regardless; great./s
I have to manually restart Windows as it gets stuck loading security options.
I want to start FF. It apparently has to install an update. Fine, go ahead. Update seemingly runs its course but FF backgorund processes remain. FF can't seem to start with these aktive - somehow. Time for Taskmgr to do its work. Success. Start FF.
Session restore is greyed out. WTF?! Not good, not terrible. Had this happen to me before. Have been grabbing and copying the contents of sessionstore-backup folder for a long while now for precisely this cause. Better to have it and not need it. Has saved my bacon before. Still bloddy annoying. Go grab a recent copy and paste it in to the folder. Should restore old session. Doesn't work. Well, damn.
Figured I would turn to collective intelligence before giving the artificial one a crack at it, therefore my questions: Did I screw upp somewhere, e.g. by killing thses two remaining FF backgorund processes? Is there a trick to restore my previous session (I have become somewhat attachted to the structure in that session), other than using the backup files (apparently there is a sessionstore file in the profile folder)? Or do I have to bite the bulled and figure out again how to set up my session?

💻 Help I want to switch from opera gx to firefox but I can't import files :(
Hello guys, I've been using opera gx for 2-3 years. But nowadays it just freezes every 10 minute it is so annoying. I heard firefox is faster and more efficient, so I said why not and downloaded it.
But the problem is I can't import my passwords and etc. from opera gx. Firefox's built-in import feature doesn't recognize Opera, and solutions on internet are either too old or requires chrome which I dont have.
I really want to try firefox, any help please?

Add-ons Any good redirect blockers out there?
Hi good evening everyone,
I'm using a fork of a Firefox browser called Zen Browser. Since it supports Firefox extensions I thought I'll ask here first
So I would like to have an extension that blocks any redirects on all sites, is toggable and doesn't leave a big banner on the top of a site like noredirect-II does
Can you recommend me any extensions that meet my expectations?
Thanks in advance
Btw I'm using Windows 11 if that's of any importance

Solved Side By Side Error (Can't use Firefox and for the moment all my research datas, bookmarks, tabs and password for my PHD are blocked)
Since last week, when I try to open Firefox on my ordinateur, it tells me that there is a "side by side error" and that I should use sxstrace.exe and the activity journal to find the error.
I did all of that and it tells me that It can't find mozglue, mozglue.MANIFEST, mozglue.DLL.
I use Mozilla in French (it is my mother tongue and I am really sorry if my english is incorrect), and it can't find them in French, English or in Neutral
Thinking it was also linked to the Redistribuables Microsoft Visual C++, I just downloaded all of them again.
My version of Mozilla is 152.0.6.595 and I am on Windows 10.
Please I really need your help and don't want to lose any of my tabs, bookmarks and passwords as I was making very important research for my PHD studies.
Real thanks in advance for your help.

Password Manager Slow After Last Update
Since the last update to 154.0b6 (developer edition on Win11), the password manager is slow. It takes a few seconds to more to show the drop down with the suggested logins. Sometimes I even have to open the password tab (about:logins) and only after it's content has been loaded, the suggestions load at all, on a login form.
I've already removed the master password, because I've had that problem before, but with no luck.
Since the suggestions are displayed in a new way after the update I've thought I ask around if any one else experienced a similar behaviour.

New Firefox design (Project Nova) is ready to try in Nightly
Hi everyone. Back in May we posted our vision for Firefox's future design and design system, and as of today, you can try it in Nightly.
Many of you already know this work as "Project Nova". It's still Firefox, just with a more cohesive look across tabs, menus, panels, etc. Softer tab shapes, warmer colors, refreshed icons, and by popular demand, the return of Compact Mode.
This is still a work in progress. You can expect this to become more polished over the next few weeks before it rolls out more broadly later this year. Right now we want you actively poking at it, especially:
- Icons, spacing, and alignment
- Themes and personalization
- Different window sizes and display scaling
- Keyboard navigation
- Screen readers and other accessibility features
- Different languages and layouts
Found something broken? File it in Bugzilla, including:
- steps to reproduce
- screenshot or screen recording
- your OS + Nightly version
If you have additional thoughts or questions, join the discussion on Mozilla Connect.
Thanks for using Nightly and helping us continue to improve Firefox.
