After a forced shut down, my home page is suddenly blank. All my tabs are missing. All my most used links are missing. All the reading suggestions and pocket is missing.

Is there anyway to restore these items?

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

On a laptop running Windows 11, all videos I play in Firefox have been strangely dark and orange. Depending on their original appearance, this can make them unwatchable.

This only affects videos in Firefox, and only on this laptop. Chrome, Windows video player (and Firefox on my other devices) do not share this issue. The issue affects all monitors I connect the laptop to.

I have attempted: -A thorough search of Firefox settings and found nothing related. -Refresh and reinstall of Firefox -in about:config

   gfx.color_management.native_srgb to true
   Confirmed ui.videoDynamicRange was set to to 0

None of these has helped. According to all the evidence I can find online, a similar issue was caused by a problem with HDR video files and fixed in an update 2 years ago, but I am running version 127.0 and am up to date.

Hello!

I am a heavy user of Firefox: daily & around 8 hours a day.

I usually use alt+shift+left/right-arrow to select a few words to the right / to the left. With the latest update (mandatory because this is a work-administered) laptop, the new behavior is that tabs are changed.

I want any solution to revert this to standard (past) behavior (preferably not an extension). Looked around in about:config but could not find anything to toggle on/off.

This is highly annoying as I've had this workflow for literally years. Even opening this ticket I encountered the issue more than 3 times as I was phrasing the message and had to delete & rewrite some stuff while also have other tabs open in the same Firefox window.

Would highly appreciate your timely response!

Thanks a lot! -- John

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

I have 2 soundcards on my iMac, (OS Ventura 13.6.1) : one internal (iMac) and one for music production. (universal audio)

Until the latest update (127), I could select either one and I could hear the audio from Firefox. But... since the update, only the internal iMac audio card is working. Note that I don't have this problem with Safari nor Chrome and it used to work on Firefox until the last update.

Anyone has noticed that? 

Does anyone knows how to contact them and log this as a new bug?

Thanks all!  :)

I know it seems like a minor thing, but I run my browser in the left hand of my screen with other apps to the right, so that gaps pushes all my pinned tabs and browsing tabs over to the right losing valuable space. It's not there on my Windows machines where I run a similar layout.

Anything that I can do about it in about:config?

I have been trying to read article comments on Fox News Digital (https://www.foxnews.com), but the comments are not showing up. I am using a MacBook Air with Sonoma 14.1. I am using FireFox latest edition and have updated FireFox but comments are still not showing up. Comments do display in Safari logged in to foxnews.com or not. I would put a jpg in this request for assistance, but it wouldn't show much just a white space where the comments should be.

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

Стало появляться всплывающее окно в центре браузера при входе на все сайты с надписью "Не позволять dzen.ru (или другим сайтам) снова вас запрашивать". Как убрать это окно чтобы оно больше не появлялось?

When I access a location-aware website, I'm asked if I'll allow it to use my location. My problem is that the pop-up window won't allow me to do anything. I can't block, allow, close the window — nothing. Is there a setting I'm missing somewhere?

Hello,

when I select a Tab and then select from the context menu -Share- I can share the selected tab which means that the URL is copied to the application selected to share the tab with.

When I select from the context menu -Select All Tabs- and then from the context menu -Share- also only one tab can be shared.

Am I wrong in expecting that all the tabs be shared after -Select All Tabs-?

Regards.

Since the last Firefox update, I've been unable to to use the tools in Google Image Search (size, color, type etc).

The text and triangles are now no longer clickable. They're all plain text and the triangle doesn't do anything.

The reason I believe this is a Firefox issue is that it's still working properly in Safari (see second image).

Is this something Firefox is working on? Or am I wrong and it's something on my end? Never had an issue before this week and I've been using the same computer with all the same plugins as always.

Is there a way to create a new keyboard shortcut to copy current tab URL?

I've been using Arc to try some of their features, and what I miss the most is the hability to copy current URL to share without touching the mouse.

Whenever I try to watch a video on YouTube, Firefox would automatically set the playback speed to max, mute the audio, and the video would just end (as if someone moved the seek pointer to the end). Since my YouTube is set to automatically play the next video, I would be presented with a screen showing me what the next video would be playing. At this point, I need to do the following:

1. quickly click cancel
2. hit the replay button
3. set the playback speed to anything but normal
4. set playback speed to normal
5. unmute audio
6. move seek pointer back to beginning

From this point on, videos would play normally and I can jump around and watch different videos. But once I close Firefox and restart it, it would reset to the above issues (max playback speed, mute audio, skip first video).

Anyone else having the same problem? Anyone know what's going on?

On a tangent, on my Windows machine, every now and then, Firefox would flash a white blank screen. I would be surfing and reading stuff and all of a sudden, the screen would just go blank. After a few seconds, it would come back. This only happens on my Windows machine and not my Mac.

Hey,

I constantly have unreadable fonts in Firefox for Mac. This only happens since I started using a new Mac (M2 Chip).

I know there are some "solutions" flagged but I cannot get it to work. My main issue is, the inspector it self has completely garbled fonts. So does the elements of the browser itself, for instance my favorites bar.

I know I am supposed to check my fonts, but I don't know how? I used the fonts application on my mac and let it validate the fonts. No issue there.

Only thing to resolve this issue is to reboot. And this is extremely frustrating since it means out of the blue my Firefox won't show fonts and I have to save all my work and reboot to be able to use it again.

I would highly appreciate a step by step solution on how to fix this. It seems to be a common problem so maybe there is a solutions that describes it better than the text I found here to inspect elements and check fonts.

Thanks in advance.
