Firefox Support Forum

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

Ver 100.0 Settings:Startup:Open previous windows and tabs is UNCHECKED. But every time I open Firefox, it opens the last site I had open before I closed it.

This worked before ver 100 and suddenly has stopped working with ver 100.

I even rebooted the computer (Win 10, 64-bit) and same behavior continues.

mazdausa.com won't fully display. I just updated to version 100 (woohoo) and tried looking in troubleshooting mode, still no luck. The middle of the page where the car (picture) is supposed to show up is blank. The rest of the site loads.

The background on the homepage link shortcut boxes keeps reverting to black and text underneath to white on my off-white background when a new version loads. I've used Colors to customize the look of my firefox but can't find any control for that. Once a new version kept the boxes white and the text black but now it's back to black again. Where is the control to fix this?

Yesterday I started having trouble logging into Gmail and associated apps (calendar, contacts, docs, sheets, shared folders, etc., as well as google.com) in Firefox. All other sites are loading with no problems. Google apps are working fine in Chrome. Still having problems today.

My office uses Google Workplace for everything so this is really messing me up, I've lost several hours of work trying to get things to load. The IT person told me that if Firefox is having problems I should use Chrome instead. I hate Chrome! I want to use Firefox, but I can't get my work done if it won't load Google apps.

Please note that I have tried the following solutions thus far: restarted Firefox (several times) restarted computer removed add-ons cleared cached web content cleared cookies and site data refreshed Firefox solution at https://support.mozilla.org/en-US/questions/1200943 solution at https://support.mozilla.org/en-US/questions/1132284 solution at https://knowtechie.com/is-mozilla-firefox-not-loading-pages-for-you-heres-the-fix/

After each fix things start working for a while but then everything Gmail-related freezes or crashes and I need to start all over again. Help!!!

I am currently creating a website in WordPress. It has many embedded YouTube videos.

On pages with embedded YouTube videos, in order to go back to the previous page, I have to click the Back button multiple times. If I right-click on the back button, I see that the page I am currently on has been listed multiple times.

Many other support questions list this issue. I have found that if I disable "Site Isolation" (URL about:config -> set fission.autostart to false -> restart Firefox), the issue goes away.

I am interested, however, in the user experience for those who will go to my site. Is there anything I can do so that "Site Isolation" does not cause this problem?

Thanks, Jeff

When playing videos on youtube or any other platform the volume is very low to non-existent. When a new video starts there is a sudden surge, whereafter it rapidly returns to a non-audible level. I have tried checking the volume settings in Windows and Firefox but nothing has helped thusfar. Please help me resolve this issue so I can go back to using my favourite browser again.

Thank you in advance!

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

Hi, With the newest release 100 my scroll bar has changed. Its now some itty bitty thin cant find unless you hover out it thing. I want the regular wide colored scroll bar I had. Is there a way to change it back?

Thank you

I haven't had to sign in for a while, so tonight when I tried and I typed the password in correctly the box just immediately closes and reopens like its incorrect. I have tried locating the key3.db and key4.db which I can't find on my system, nor can I find the login.json that is supposed to have the log of passwords to back them up. I don't have any 3rd party password managers and I've tried with my VPN disconnected. I've used the password generator to secure some of my websites so I don't even know was some of my passwords are, so resetting the primary password would be a huge hassle. If someone could please help me out I would be very appreciative. Thanks!

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

I don't mean "saving" login information for later use, that I do not want to do. What I mean by the login not being retained is that when I log-in to a website like say Amazon, while I'm browsing, I end up having to re-enter my login information pretty much every other time that I switch between pages. I've never had an issue like that with any other browser. Is there some setting I need to adjust to stop that from happening? As I said, I'm not looking to save my passwords and usernames within the browser, I just want to effectively browse a website after logging into it without needing to login every time I move between pages. Thanks!

Subtitles in picture-in-picture are doubled. I've tried clearing the cache and restarting the browser but the problem persists. Site in question is Netflix (first image). Does not happen on YouTube (second image).

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

I would like to stop the default behavior of firefox displaying in the tab that contains my GMail how many unread GMail messages there are -- in other words to delete "(9)" from the attached photo and never have the count displayed -- if it could instead simply say "Inbox - xxx@gmail.com"
