Firefox Support Forum

I was attempting to reduce the size of the tab bar using about:config and I screwed up making everything so small I can't determine where the setting is to change it back. What can I do to get it back to normal, preferably without losing all my shortcuts?

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

I appreciate the quick reply from your support staff yesterday. I followed instructions and was able to turn off the GIFs but FOR ONLY ONE TIME. As soon as I exited Firefox, or even the current page and returned to it they were back on. How do I keep them off permanently?

I do not want the new color browser. I absolutely detest it. I want to go back to what it was, normal. How do I get this hideous green color off the top of the browser

Hi all,

Recently, my win 10 crashed and although I managed to recover some operative, I found to my horror that the desktop screen text size and contrast cannot be changed now. The current default setup is a real eye sorer, so I opened personalization settings but there is nothing on how to change this very theme, other than other posts suggesting entering the regedit system files. I am very reluctant to tinker with this given the Win10 application crashes. Running maintenance doesn´t do much. I notice that Firefox also has access to this very text size and font theme for web domains, but I am very wary again of tinkering an unknown. What the heck can one do, confidently without the system resetting itself? One thing is for sure, it seems Win10 home edition update 21H1/2 versions is basically treating users very badly, as if MS wants to ignore them. Bless us all when the embedded caption suggests "ready to update to Win11". I´m highly inclined to bin it.

Hello Lovely Firefox Volunteers,

I hope this email finds you well. I am a long-time user and fan of Firefox, and other open source projects. Firefox is a fantastic internet browser!

Having said that, I was shocked and dismayed at what I encountered today. I was doing some tests for screen-reader usability on a website, and I came across the following:

Image 1 (attached): Advertisement of Screen-Reader Add-Ons for Firefox

Image 2 (attached): No Screen-Reader Add-Ons for Firefox are Available

The Firefox team is advertising screen-reader add-ons for Firefox, which don't seem to exist. I don't think the recommendation here should be: take down the advertisement for the Firefox native screen-reader add-ons/link to them, these seem to be really important for accessibility, and the Firefox team seems to acknowledge this. :)

There is some other missing piece - maybe there are Screen-reader add-ons for Firefox, and they aren't being linked to? Maybe the wrong tag is being used? (The auto tag that is used in the link is "screen reader"). Maybe there aren't any, and this is an area that needs some additional attention?

Anyway, I just thought I should bring this to your attention as making our internet accessible to people living with blindness and loss of sight is extremely important.

Sincerely, Katie

I use the recent activity page as a homepage with the icons of the websites that I most frequently use. but i can't figure how to adjust/pick the icons (websites) that I want to appear on this page. Something is picking them for me. And when I delete an icon another one pops in place but is generally a website I rarely use. How can I choose the icons (websites) that I want to appear on this page?

Hi guys. So, I have Avira free antivirus. Can I still install for example Norton web security addon for Firefox? Will there be any problems between my installed antivirus and the Norton addon? Sorry if this is a noob question, but there you go :) Any help would be appriciated. Thanks in advance for any reply.

I was trying to change Firefox's font size to 2, (in about:config) but accidentally typed in 22. Now the screen is so zoomed in that I can't use the browser at all. It's so close-up that the only thing it's able to display is the corner of the menu bar. If I try to access troubleshooting mode, I obviously can't, since it still will only show the corner of the page. Since it's the font that's the issue, and not an actual zoom option, trying command/control -/+/0 doesn't work either. I can't make the page wider, longer or pull it to the side to attempt to see other parts of the page, and I can't scroll down, up, sideways, anything. I feel like I've tried everything, and at this point I'm worried I'm going to have to make an entirely new Firefox account or something just because I mistyped one number, which I really don't want to have to do.

Feeling like a real idiot, please help me. Attached an image of what the page looks like whenever I open Firefox.

I set my browser theme to a customized green theme I made myself with firefox color, then I decided I wanted something different and installed a new theme from the addons page. It works until I close firefox, but if I open it again it changes back to the custom one I made? I can't find any settings that fix this and i don't want to delete the custom themes I made just to be able to use one of the addon themes I have saved.

All my menu texts are so TINY now, that I can't read them, but the browser page is SO WIDE that I can't ever see a whole page and I have to scroll from side to side to read things, which is a ROYAL PAIN as I miss seeing a lot of things. No one can seem to help. I tried the limited percentage things, 67% used to work but now that is too big and when I go smaller I can't read ANY of the text, it is TOO TINY! I can't do my work! The screen shot won't paste on here.

When I right click Firefox in my taskbar I have a list of "recent" links show up. I have turned this off in about:config but they still show up. Any suggestions?

When I start typing URL's in Firefox, it will only ever suggest the URL so far as the top level domain. For instance, I frequently visit trakt.tv/dashboard. But when I type "tr" into the URL bar, Firefox only ever suggests trakt.tv - I have to manually press the forward arrow key and type in "/d" in order for it to autofill the rest. It doesn't matter how many time I type the full URL in or even the fact that I've deleted all history only visited trakt.tv/dashboard, Firefox will still only autofill trakt.tv

Is there some about:config setting I can change to make Firefox recognize and prioritize specific frequently visited URL's over just top level domains?

See images. The buttons on video players don't look like play, pause, gear, etc. They look like gamepad buttons. But a gamepad is not connected to my PC and I haven't connected one in months. I have tested it with videos on invidious.snopyta.org and tagesschau.de.

I cannot disable google document viewer in Google Drive. Every time I go to open a recently downloaded PDFs in Google Drive, it invokes Document Viewer unless I specifically right click and tell it to open with Acrobat. I have disabled everything thing I know in both Chrome and Firefox, cleared the caches, rebooted, and the default behavior persists. Worse, the Document Viewer REQUIRES a complicated, infuriating sign in process that has only worked ONCE in dozens of sign in attempts. Please help with this.

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

Dear Madam or Sir,

since updating to Firefox 99, we are unable to view PDF files in Firefox, because we are unable to select how to handle PDF files in the settings, cf. 1.PNG We don’t have any enterprise policies enabled except for disabling updates, cf. 2.PNG. We tried disabling hardware acceleration, but it did not help, cf. 3.PNG We tried safe mode and an empty user profile, both to no avail.

This problem seems to be irrespective of the user profile because when I roam my user profile to a machine with FF 93 ESR, there is no issue and I can view PDFs in the browser.

Is there any suggestion how to return the built-in PDF viewer?

Thank you very much in advance!

Best regards

Victor
