Firefox Support Forum

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

If I open two windows of Firefox, pin tabs in the first, close it and then close the second window, my tabs disappear. In order to use this feature one must work with only one instance of Firefox?

Hello! A site kept popping up a confirmation window for an action I was trying to take, and in the confirmation window, there was a checkbox for something like "don't allow [this website] to prompt me again" (that's as best I can remember). I checked the box thinking it would just allow the action to happen without the confirmation window, but instead, the site just won't take that action anymore. How can I undo this setting? Thank you!

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

I have been trying to watch Netflix on Firefox, I made some security changes and at first thought that I may have caused the problem, but now I see that the add-on just fails to install. It just keeps the notification that it is installing. Is there a way to fix this issue?

Ever since IE changed to tabs on top firefox coders followed like mindless automatons without any regard to/for Mozilla community and users. We are sick and tired of being ignored. We want/need tabs bellow address bar. Now, tell us how to simply get tabs below address bar or tell the coders to provide us with the option. And, we don’t care about any excuses as previously provided or outright ignored by them.

Hey there, awesomes! I'd like to change my Firefox pdf viewer's background color (both sides of the pdf) to dark, currently it shows light gray (see `background_bg.png`). And here is effect I want it to look like (see screenshot from Chrome `wished_bg.png`). Thanks in advance (:

PS: I don't want to change my theme to dark. It seems I have to change my css, but I dunno which & how.

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

Today I've refreshed my Firefox and I'm aware that I'll loose all my add-ons/extensions/customization's, but the problem is I've lost all my passwords in my Firefox lockwise! Please help me. I need all my saved passwords ASAP.

On screen keyboard not working when using Firefox. It will work with MS Edge, but not Firefox. It flashes then disappears quickly when in Firefox. It worked previously, but a few months ago it quit working.

I "upgraded to V90. since then, the URL box is highlighted red/grey stripes. The robot head icon is now in the URL box and it says "Browser is under remote control (reason Dev Tools). I've gone in about:config and set all variables to False, yet they reset themselves to true every time. How do I disable the DevTools. Thanks

Just ran a search in the address bar and was taken to this "Firefox search contest 2020" page. Never happened before and I assume it's a scam, have checked my add-ons and plugins but I don't see anything suspicious. Is this something to be concerned about?

Hello Everyone

I'm having troubles with playing some Youtube-Videos and Twitter Videos. I had to re-install my Windows 10 (64 Bit) due to some hardware-issues which are not related, and I'm having this issue since then. Here are the steps that I already did:

-Removing all Add-Ons -Starting in Safe mode - Deinstalling and reinstalling Firefox, then starting in safe Mode -Deinstalling Firefox with a tool that also deletes all Firefox-Related Registry Keys and App-Data Files and reinstalling it to a different path (other HD) -Disabling add-ons - Disabling Open264 Videocodec and widevine content decryption module (more just because of frustration^^, but I was then able to play some Youtube videos after this one) - mediasource.enabled is active (and all the other ones as well) -Installed addons (even though it didn't work with them disabled as well): NOscript( youtube videos are allowed, some of the are working), Ublock Origin, Video Download Helper, HTTPS Everyhwere, Tree Style Tab, Limit distracting sites - Updating to the newest Firefox-Version (which came out today)

Btw: on https://www.youtube.com/html5/ it tells me that everything works fine and I have of course the newest Firefox-Version installed.

Do you guys may have any other ideas?

Thank you for your help.

Kind regards,

Gabe
