Spell checking does not work with Outlook Web Mail in Firefox. This issue has been raised by many others but I find that the answers and solutions don't match my user interface and aren't really solutions. This seems to be a widespread problem and I really feel that Mozilla should solve it. Otherwise users like me will likely need to change browsers. - I am using the latest version of Windows 11 and Outlook Web Mail. - My Firefox is up to date (144.0.2) - Spell checking works if I switch to plain text. Thanks for any help with this matter. Mario

Log onto Firefox. Go to Yahoo mail, log off this and yahoo homepage shows daily pop up which is some sort of counter ("Don't ghost us" day 1,2,3, on on Google says this is a browser issue, Redirect to Chrome same thing. Have adblock on. All settings on all 3 browers do not stop it

I recently experienced [not previously] in trying to print a received e-mail using the "print" item. When I clicked on the "print" word I received the following error

Please advise how/where I may change a setting to avoid this error

I lost the key and am unable sign in on my Mac Book Pro. Just received cable. Hopeful that I haven’t lost bookmarks and passwords Can I get step by step if possible Thanks

this is a request. i have maybe 100 tabs open at any one time to support my research projects. i've recently used the group tab function--thank you Mozilla--but now i find a need to go to a group directly. firefox view does not currently support a "sort by group" function. it has sort by recent activity and sort by order, and a general search function. but it would be great if it could also sort by group in firefox view, too. can do? thank you, C Baron

Docusign does not work through Firefox anymore. However , it does work with other browsers. I have emptied my Cache and deleted and reinstalled Firefox with no luck. Any suggestions?

When doing a search I receive a message " Secure Connection Failed

An error occurred during a connection to af.xdock.co. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG"

How do I fix this issue?

Hello everyone, I manage a website, which focuses on mobile phone prices and SIM package information in Bangladesh. I’ve noticed that the site loads noticeably slower in Firefox than in Chrome, especially on pages with large images (like smartphone price lists). I’ve already optimized the images using WebP and enabled LiteSpeed caching on my server. Are there any Firefox-specific performance recommendations I should try (for example, about image lazy loading or compression settings)? Any advice from developers who’ve optimized for Firefox performance would be greatly appreciated. Thanks in advance.

Dear, When playing a video on Youtube, Jellyfin or listening to the radio the video stops after a second of playing. Restarting FireFox works for a short amount of time and after that constant pausing of video's after pressing play. Really annoying.

What I allready tried - What is pressed --> none - Rebooting PC --> 5-10 min fix - Restarting FireFox --> 5-10 min fix - Updating FireFox --> Was on the newest version of 28 OKT 2025 - Updating Windows 11 --> Was on the newest version - Problem Solving Mode (So plugins/addons disabled) --> No fix - Chrome --> Works perfectly - Brave --> Works perfectly

Any idea's/fixes

description in German:

Ich habe vor langer Zeit ein Addon installiert. Jetzt wollte ich Firefox neu dekorieren. Deshalb habe ich das Addon in die Sidebar geschoben. Unten links in der Sidebar war dann der kleine Knopf für das Addon. Dadurch konnte das Addon aber nicht auf den aktuellen Offenen Tab zugreifen, jedenfalls hat es nicht funktioniert wie vorher. Also hab ich auf das add on Rechtsklick gemacht und es aus dem Sidebar gelöscht. Es ist jetzt nicht mehr in der Sidebar.

Leider schaffe ich es jetzt nicht mehr, das Addon wieder als Knopf in der oberen Leiste also über den Lesezeichen zu platzieren. Es taucht noch auf wenn ich den Knopf für Addons drücke, und es aus der Liste auswähle.

Kontext: Firefox on Windows Addon, was ich verschoben habe: Addy.io

Problem: Ich will das Addon wieder schnell öffnen können. Es ist nicht weg, es ist nur woanders.

Wie füge ich es wieder der Symbolleiste (oder dem Overflow Menu) hinzu?

My desktop (WIN 11, fully updated) Firefox (reloaded yesterday) does not play well with Google's Blogger. I maintain an open tab on my Blogger account, but that SEEMS to cause freeze-up on all other tabs. THis morning I opened a tab and attempted to sign in to Blogger but a connection to Google never came through. However, when using Edge to open/use Blogger there are no problems.

Hello, I reinstalled Firefox and am unable to recover my bookmarks and other data. Before the re-installation, I manually backed up my data, but when I try to restore from the backup, it does not work. All my bookmarks and previous data are still missing. How can I fix this and recover my information?

Hi guys,

I'm on my personal computer and personal account and my "network administrator" (which I don't have) has turned on restricted mode in YouTube so I can't read comments on videos etc. I know I need to change my browser security settings, but I don't know to what exactly. Can anyone help? The restricted mode is infuriating me.

Hello,

I recently installed a new add-on in Firefox — the one that allows you to create different profiles with individual names and colors in the browser.

After the installation and a subsequent restart of my MacBook Pro, my previously open session windows were not automatically restored when starting Firefox as usual. Instead, a message appeared asking whether I wanted to “restore all session windows.” I clicked “Yes,” but none of my previous windows opened.

Since then, my saved passwords and bookmarks also seem to have disappeared. I suspect that my previous profile may have been overwritten or that a new profile was created.

Could you please let me know if and how I can restore my previous sessions, bookmarks, and passwords? Is there perhaps a way to access my data through a backup or via the sessionstore.jsonlz4 file or an older Firefox profile?

Thank you very much in advance for your assistance.

Kind regards, Diamant Adler

When trying to upload a file to sharepoint or service-now, I get the following error: You don't have permission to open this file. Contact the file owner or an administrator to obtain permission.

The operation works in other browsers.

I have disabled all extensions and add-on's, tried in safe mode, private browsing mode, reviewed Windows security, application and system log files.

I'm not finding anything in the Web Developer Tools either.

Has anyone run into this before?
