Using Firefox for webmail, There used to be an option to spellcheck a "Composed" message before sending it. Probably after a recent "upgrade", that option seems to have disappeared. True? Can I get the facility back in some way?

In my settings under Connected Services there is a list of devices that have signed into my firefox account. I do not recognize one of them. The Connected Service listed name is Firefox Mobile 126, Android 14. How can I find out where this is coming from?

Thank you

I started getting "can't load XPCOM" errors when starting Firefox. I did a full uninstall, then attempted to install the new version, I still get the same error during the install.

Hello According to this thread I set the values:

«browser.bookmarks.openInTabClosesMenu» → «false». «browser.tabs.loadBookmarksInBackground» → «true».

But when you click on "Open All in Tabs" in the bookmarks menu, it redirects to the first tab to open, that is, the value "browser.tabs.loadBookmarksInBackground" does not work.

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Hello, I am a tinkerer and I would like to tweak my Firefox Developer Edition to suit my tastes, but I don't know what each of the preference commands does. Could you provide a list explaining what each command does and, if possible, how to use them? I don't want to reinstall Firefox.italic text I prefer to do things properly. Thanks

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

I have just udated nightly. the tab hover shows a bunch of useless info. is there a way to get rid of it? apart from the image, that seems to be tweaked ibn settings for now, I don't need such a verbose mode. every usual surfer needs just and extended reading of the page title, that is usually cut when you have many tabs. I switched to FF because chrome conf made it unusable. hope FF isn't going into the same direction. Thanks for any help. andrea.

The website mylotto.co.nz has been blocking Firefox for many months now and when I rang them to find out what the problem is they just say they are having problems but it was obvious that the person there was reading a script and fobbing me off. This has been going for many months now a problem would have been fixed by now. I would like to know if you can bring pressure to bear on them to get reinstated again. I have attached a screenshot of the message from their site. Thanking you. Murray

When I try to access Developer Community from Visual Studio 2022 ('Send feedback' 'report a problem') the banner displays with selection items but no content is displayed. This has been a problem for several months (years maybe). I now have a problem that I cannot solve and I need to report it and I cannot if content is not displayed.

Video in Firefox does not run .. no error messages .. nothing. It works fine in other browsers. When I click on the video .. nothing happens. It used to work but not now and I don't think I've changed anything.

previously I added bookmarks to a menu bar at top of firefox. Now I have a bar that displays 2 bookmarks than a >>. I cannot expand this limited display or create a menu to display bookmarks though I can see them by clicking on the >>. Non of the menu suggestions is a fix.

Does anyone know how to control this and get me a more useful bookmarks menu display?

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

Hi. I am getting vertical lines sometimes. I have included two screen shots. I have checked browser.display.document_color_use = 0, and it was zero. I have tired this in Chrome and it works fine. And I tried in Firefox safe mode, and it still does these strange lines on some websites. I am running Windows 10, and have no other graphic issues except these lines. Websites are Windy.com and google maps. Thanks very much! James
