Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

Xfinity streaming works on Chrome and Safari but it stopped working on Firefox a few days ago. Why? I am using the latest Firefox version 140.0.4 (64 bit) and I can only receive my emails. The connection to the streaming service does not open. The Xfinity logo just sits there spinning and no connection. Please fix this. I much prefer Firefox to other browsers BUT....

Before upgrading to Firefox 140, I would always quickly switch between my default DuckDuckGo and alternative search options, like Wikipedia, using the up and down arrows. I would just type the search term in the address bar and then tap the down key a couple of times before pressing enter if I wanted to use a different search engine.

The new address bar no longer seems to offer this option. I see I can still select alternative search engines using the mouse, but pressing the down key no longer lets me select them.

Is it possible to re-enable this way of quickly switching between search engines using the keyboard?

Don't know how to describe the issue. I leave the computer on all night. In the morning, when I move the mouse to activate the screen, there is a large, 3-panel image with links to various websites. Today's panels are titled "Daily Wonder," "Hats Off to the Class of '25," and "Markets." A click on any of these panels takes me to a website. No idea how these panels are produced or by whom. If I try to take a screenshot, the images disappear and my normal home screen is shown. I do not recognize anything in the Task Manager that might explain this. Not sure if this is a Windows issue or a Firefox issue. Perhaps another user can ask me questions that will lead to more information.

Windows 10 version 22H2, OS Build 19045.5854.

Thanks, Cloverdavid

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

After updating firefox from 128.8.0 to 128.9.0, no embedded videos will play (youtube, instagram, plex, etc...)

The only way to get them to play is to run the browser in troubleshoot mode. Even a fresh browser profile doesn't work. Disabling hardware acceleration also does not work. Tried firefox 137.0.2 and that also does not work. Downgraded back to 128.8.0 and videos play flawlessly again.

I'm running firefox on gentoo linux on a thinkpad x13s (arm64) which uses Qualcomm Adreno 690 graphics.

Anything I should try would be greatly appreciated. Thanks.

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

I keep getting nuisance popup prompts to sign into an old gmail account I had linked to my firefox program. I have since deleted this email from firefox and closed the gmail account but keep getting these popups asking me to log into this old gmail. How do I fix this??

Hello,

My experience with Firefox has been great for more than 15 years. However recently there's been a trend of adding new functionality without asking the user whether they want it or not. Moreover, some things cannot be disabled even if I try hard enough.

It was an unpleasant surprise to discover that "This time, search with" panel was removed without my consent, and is now replaced by an extremely inconvenient button. I firmly believe that this is not how UX design is done, and whoever made that choice needs to reevaluate their decision.

How can I revert this change besides rolling back the browser version?

The setting "browser.urlbar.scotchBonnet.enableOverride" did not help, it reverts to *true* on every restart. I have not been able to find any other settings, and I believe that this is not something that a user should do their research on.

Is there a way to affect this change?

I updated firefox, and all my addons and sign ins are gone now. Search history and tabs remained intact. It also created a folder on my desktop, but I'm not sure how do I "extract" my old data from it.

The comment sections for foxnews.com and other sites disappeared using Firefox but not when I switched to Chrome. This just happened 6-18-25. Before this date, it worked on Firefox.

Periodically I open Friefox and all my cookies have been deleted. I go into settings to find "Delete cookies and site data when Firefox is closed" has been checked (NOT BY ME!) again. This is very annoying as I then have to log into all my websites and go through 2FA. This is annoying to the point that I am posting on this site for help. Next step is find a new browser that doesn't screw up my work-flow randomly for no reason.

Здравствуйте. При воспроизведении видео на каком либо сайте в полноэкранном виде не скрывается панель задач виндовс. На других браузерах работает как надо. Менял где только можно, даже в безопасном режиме также. Как её можно убрать?

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don
