Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

Hi, Today I discovered that firefox has logged me out of every site. I checked the cookies and there were cookies.sqlite and cookies.sqlite.bak. When I delete the newly created cookies.sqlite and rename cookies.sqlite.bak to cookies.sqlite, I am logged back in to all sites and everything works fine. I notice that the cookies.sqlite.bak file is created when I go to twitch.tv. Can I check what is causing this problem and fix it somehow? I've already tried deleting the cookies just from the twitch.tv site, but that doesn't help.

Firefox automatically updated itself to version 126.0 (64-bit) and it was unable to display any web sites.

First I disabled Mozilla VPN but that did not fix my issue. Next, I disabled Microsoft Defender firewall software to no effect.

Finally I updated the shortcut to Firefox on my taskbar to launch the browser. This fixed my issue.

Hopefully, this will save other users from the same pain.

Dear all, I would like to know how to disable the automatic insertion of the tag
in a text editor in Firefox. I am using Froala, and I am experiencing this only in firefox. Chrome and Edge do not add this tag automatically. Thank you for you support. Kind regards, Cristiano

I've added https://x.com as an exception site but it is still blocked.

This is outright censorship which is something fascists do.

Tell me how to fix your browser so I may access x.com again or I stop using Firefox forever.

I just updated to the latest version of Windows 10, and now when using Firefox (126.0), the url dropdown menu rather than dropping down now "floats" over the browser window with the top cut off. The top url is still there, and I can navigate to it using the arrow keys, but it doesn't show. This is new as of this morning, when Windows updated. No issue in other browsers.

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

확장프로그램을 설치했는데, 원래 대로라면 브라우저 상단 주소창 옆 도구 모음에 설치한 확장프로그램의 아이콘이 나타나야 하나 나타나지 않고 있습니다. '도구 모음 사용자 지정'으로 들어가서 직접 추가하려고 해도 추가할 수 있는 아이콘이 나타나지 않습니다. 이 외의 방법으로 사용할 수 있는 방법을 아무것도 찾을 수가 없는데 대체 어디서 어떻게 찾아서 어떻게 사용해야 합니까?

i installed a add-on program however this icon for using is not shown on browser's menu bar. there is not on personal setting, so i cannot find how do myself. wat should i do?

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

I recently had to reinstall Windows, as a result of a hard drive issue. This involved reinstalling Firefox from scratch.

As such I had browser.sessionstore.resume_from_crash set to false, but browser.sessionstore.max_resumed_crashes was still set to its default value of 1. The combination resulted in a browser restore after a crash...

This would seem to imply that browser.sessionstore.resume_from_crash has either been deprecated (though that is not mentioned in the knowledgebase article), or it is not being correctly interrogated in the code. Unless I am missing something, and I do not want to go thru the entire config to see what else I might need to set...

If I am reading this wrong, please let me know if there are other entries that need to change from default. In the event of a crash, I want the browser to start with my home pages, NOT restore.

Currently on FF 125.0.3 (64-bit) - and yes, I know there is an update waiting for me to restart my browser yet again...

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

Hello, How can we disable QUIC with the latest ADMX or via registry entry on Windows 10. I see not settings under ADMX that can assist in doing so. I dont mind implementing a registry entry in GPO as well.

Thanks

Hi folks,

I've searched, but I haven't found anything to help with this particular situation ...

I love Firefox/Mozilla Sync and I use it a lot, but I've recently had a desire/need to set up a scenario that some may think perculiar - let me set the scene ...

• Work PC running Firefox - 1 profile
• Work VDI running Firefox - 1 profile
• Work laptop running Firefox - 2 profiles (work & personal)

Mainly for the sake of sending tabs to the appropriate Firefox profile on the laptop, I want/need to be able to config things in Sync to treat those 2 profiles as being different entities. Currently, it appears that all profiles on a device (or within the same user profile on a Windows computer) are treated as the same entity by Sync.

Any ideas on how to achieve what if trying to do? Is it possible with Firefox/Mozilla Sync?

Thanks for your time.

BTW., for clarity, if it matters, the devices listed above are all Windows. FWIW., I also use FF on Android and Linux ... and MacOS.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

slow browser takes long time to change screens & i have hi speed inernet & side skrool bar works half the time &stay loged in dont work makes you log in evertime fix website

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!
