The same happens in troubleshoot mode. I also tried reinstalling an older version but the same thing happens. Help me figure out what's wrong so I can read emails. :(

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.

I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

Firefox mobile android version 125.3.0 (Build #2016017559), 9f29904153+ GV: 125.0.3-20240425211020 AS: 125.0.1 On a samsung galaxy note 20 ultra 5g.

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

When trying to configure my gmx.com email with Thunderbird I get this message when trying to create a new account.

Component returned failure code: 0x80004005 ▲ (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

I have set the email up many times before just never with Thunderbird on a Linux setup so I am not too sure what would be causing this, trying to find help for this I come across the same issue with varying differences. At first I thought it maybe my firewall but I disabled it and tried again and still same error. Any help much appreciated.

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?

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!

When I create a task in Thunderbird I can use the formatting options, like a changing the font to bold or add a bullet or numbered list. After saving the task all this formatting somehow completely disappears. How to solve this?

I have made Firefox my default browser, and set Google as my default search engine.

I'd like to keep it that way, BUT ...

Every morning when I come to work and open my browser and begin to search .. Yahoo comes up .. or Bing ???? I delete them, and again set Google as the default ... BUT FIREFOX CONTINUES TO REVERT TO YAHOO, or BING SEARCH RESULTS  ?!?!?!?!?!?

Even when I deliberately open Google and search in Google .. the results appear and then suddenly, a new window pops up with Yahoo results, covering up the Google results????

How can I make Firefox respond to the default search setting I choose????

This is intolerable. If I can't get ride of Yahoo and Bing and all these other inferior search engines, then I'm going to go back to using Chrome.

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

All of a sudden, Firefox (125.0.3), running on Windows 11, is not delivering any sound at all on websites which have music or people speaking. The TOR browser does deliver the sound on those same websites.

I have installed Firefox on both my tablet and Phone (Android 13 and 14). I cannot get a QR code on my desktop when I follow the link but I did get a QR code from another source but I was required to give a code on my Microsoft Authenticator but none appeared. I have set up two-stage authentication but am not receiving the required codes. Can you help ?

Thank you

I run message filters to file messages from Inbox in specific folders. However for some of my filters that copy or move a message to a folder in Local Folders the body of the message disappears, leaving only the message header. Other filters set up in the same way work fine. The filters are usually on the sender's e-mail address. Any ideas for a fix?

Been using Thunderbird/Lightning for many years. In the latest update (115.10.1 (64 bit)), the EDIT button is not initially visible when I click on an event in my Calendar. In past releases, this edit button has always been visible in the pop-up window when I try to edit info in a New Event task. This happens SOME of the time, but not all. Any idea what changed, and is it possible to check out the code and change it back so when I double-click on an event, I see the edit button. At this time (not a big deal, but slows me down), when I go to edit an event, I have to move to a different monitor, resize the pop-up window so I can see the EDIT button, then finally click on it to edit the Event. In the past, the cursor immediately went to the EDIT button. Any info on changing this back the old way would be appreciated.

This randomly happened over the past few months but last couple days it's bad. The Google Sheets cells I have open on Firefox turn black. You can scroll and they will come back but just briefly and back to black. Very annoying as these are shared sheets for my business with other employees. It's not happening in Vivaldi Browser or Edge. I hate Chrome so not even trying it there but guessing it's fine. Seems to just be Firefox all of a sudden. See pic. Help please as I have no clue what's causing this.

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.
