Firefox Community Forum

Losing my mind on this one.

Have 2 Macs I use at home, both running FF 141.0 and Sequoia 15.5.

Use Reader for RSS and Airmail for eMail. Both have settings to allow links clicked in those programs to open browser tabs in background. Handy way of banging through newsletters and RSS feeds before shifting to browser.

One on Mac, that open in battleground setting on both apps works as it has for, oh, last several years. On the other Mac, a few days ago that open in background stopped working with Firefox. It does work properly on Chrome and Safari if I set them as default browser (and, as I mentioned above, on my other Mac).

I've tried resetting Firefox on this Mac using the troubleshooting menu and have also cleared the Firefox cache. I even tried resetting the launch database in that Mac, although the fact Chrome and Safari are working fine suggests the OS isn't the culprit.

I'm unaware of having changed any settings, but am aware that "idiot user" may be the issue.

Regardless of how this happened, any ideas how to sort this annoyance out? Thanks!

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

I have an extensive collection of saved files. Almost all are saved as pdfs, except a few word files. Recently Firefox has started to save them as html, which is incredibly irritating. How do I get Firefox to save them as pdf?

I am logged into my computer. When I try to sync my phone Firefox with my computer, I am asked to provide a number from an authentication app. I don't have any such authentication app and can't figure out what the Firefox one is. There does not seem to be a workaround. I can't use a backup code or reset option. I am trying to figure out what to do.

Thank you

Recently, in the past month, when I open PiP to play videos (mainly Youtube) and open another tab play web game at the same time, the web game screen will be slightly stuck, and there is a high chance of triggering VIDEO TDR FAILURE.

I'm not sure if this problem is caused by PiP, but it only happens when I open PiP and a web game at the same time. It happens about 2-3 times a week, and I haven't updated my graphics card drivers recently.

OS: windows 10 Browser: firefox 141.0 Graphics card: GTX1060 Graphics card driver: 32.0.15.7688

I am frustrated by not being able to get these two extensions to work: ClearURLs Copy-n-Paste: Clipboard Upload Simplified

ClearURLs doesn't seem to do anything. URLs do not get cleaned as expected. Copy-n-Paste: Clipboard Upload Simplified just doesn't work. It gets invoked as expected but does not recognize clipboard content nor let me browse for a file.

Could there be anything within my Firefox that is causing the problem? Can live without ClearURLs. I was excited to find it but have been cleaning URLs manually for a long time so all I hoped it would do is save me some effort. OTOH, the Copy-n-Paste extension would allow me to make Firefox my default browser. I am very active in a number of support forums and often post screenshots. The inability to upload clipboard content when using FF makes it too inconvenient to use for these forum sites. Vivaldi and Startpage have this functionality built-in so one of them gets used. I prefer FF as a browser though so I wish I could get Copy-n-Paste to work. Thoughts on how to do that would be appreciated. Other installed extensions are uBlock Origin and Privacy Badger. They both seem to work fine.

Mozilla is using an old email address (df228h@icloud.com) and won’t allow me to add a valid email I use daily. (df228h@gmail.com) which it says is invalid when I try to add it as a secondary email.

I'm one of those people to whom sub-pixel smoothing just looks like a colored blur. However, there seems to be no way to disable this. Firefox seems to ignore my system settings in this regard. Did I miss something in the settings?

I am getting a lot of web client exceptions with version 141. How Can i go back to version 139. This is for my work software. I have no power to make changes to the software. If I can go back an not have automatic updates that would be great. Will I have to delete firefox and download an older version.

Hello if i enter proxy and ip address in firefox in Manual proxy configuration section then when i open a website its asks for username and password my question is can proxy owner see my data and i am using https websites like post data ?

I currently have NordPass as a Firefox Extension. After checking a box for "Stay Signed-in," I can no longer turn it off. Instead of any unauthorized person signing in with Firefox, I want to need my Master Password in order to sign in to websites. How do I stop this "Stay Signed-in."

All of my extension buttons disappeared, both from the main toolbar and from the Extensions sub-menu. They are still installed however. The only entry visible in the Extensions button, or in Manage Extension Shortcuts, is for an extension that has no button (Markdown Viewer).

This issue persists even if I switch to a known-good backup of my profile.
