Forum der Gemeinschaft Firefox

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

As of lasts night Youtube has stopped loading. After reading some support articles I reset my browser and turned off nearly every extension and setting I could find and got it to load once, but then it stopped again. Navigating to Youtube brings up a grid of squares (which I believe should be stills for videos). I turned the extensions back on and tried turning them off one by one but I'm unable to isolate on that's causing the issue. Similarly, I tried settings one by one, but cannot find one that resolves the issue. Using the one normal open Youtube window I have, I am able to open a video in a new tab, but there is no menu on the left, no links on top no comments, I can't even like a video.

I can not get Youtube to load on desktop Firefox. It works fine on the mobile website, app, and Chrome. I've tried clearing cookies and site data, removing extensions, resetting Firefox, and disabling hardware acceleration, and so far nothing has worked. Has this been happening to anyone else ?

Suddenly today (April 30) when I try to go to Yoube home page, I get a blank (see the picture). But if I try in a private window, it works.

I see Youtube has re-designed its home page - maybe that's part of ther problem.

Is there a setting I can change?

After Update to 138.0 my sideabar (bookmarks) is away. I can reactivate the sidebar on the left side as wished. But when I open a new Firefos Window or Tab the sidebar ist away again. What have they done, mozilla ?? How can I get mey bookmarks ALWAYS shown on left side of any Window or tab ?

Hello, I'm a blind, screen reader user. I've used FireFox and Thunderbird for years. In the last month-ish something has changed in the Update Dialog for both apps, that asks if you want to allow the app to make changes to your hard drive. With Jaws and NVDA screen readers, this dialog has normally spoken, so I can Tab to the Yes button, press Enter, the update happens and all is well. Suddenly, this dialog doesn't speak... not a word. Don't know where I am at all. I've tried pressing Alt-Y, which is a Windows accessibility standard for pressing a Yes button, but that hasn't worked in the past, and doesn't work now. I am blessed with a sighted husband. When this dialog has come up in FireFox and Thunderbird the last month, he has kindly bailed me out and clicked Yes. But this is a nightmare accessibility problem. Using only a screen reader there is no way out of this. Escape doesn't get rid of the dialog and just not update. The dialog sits on the screen, not speaking until you take some action. In fact, the first time this happened I couldn't figure out what was going on, but tried to handle it myself. Nothing talked, so in the middle of things, I used the power button to shut down. Well... we think I shut down in the middle of the app attempting to update. So my laptop came up with an error on the screen, and we actually had to use my husband's computer to get into my Microsoft account and dig up a huge numeric code that would allow my laptop to boot. It was bad and took a long time, and my husband is a saint. So... something changed about a month ago in the Update Dialogs for both FireFox and Thunderbird, that causes them to no longer be readable by screen readers. There is not a keyboard way to just press Yes. There's not actually a way to know for sure that the reason the computer won't talk is because this Update Dialog is sitting on the screen. The developers need to know this has happened and fix it. I don't know any other way to reach them. Thanks!

Hello. After updating to Firefox 138.0 (20250421163656), an issue has appeared that causes incorrect transparency behavior in the taskbar. The problem is that Firefox expands to full screen but continues to operate in windowed mode. After enabling full-screen mode (F11), the issue disappears until the next interaction with the browser. Nothing critical, just a bit annoying.

A banner appears upper right of screen, stating firefox has 3 notifications (or 1 or 2 etc) but I don't know where to look for them. Can anyone help? I'm using a MacBook Pro from 2010 (when they knew how to make things that lasted) with firefox version 115.22.0esr on macOS High Sierra 10.13.6 (which is apparently the last version I can use as computing has vastly outraced my laptops capacity and we are expected to update everything to catch up with security glitches etc so tough sh*t if everything goes wrong. Welcome to capitalism folks.)

Ahem, but I was saying: where are these notifications and why isn't it obvious?

After using Firefox as my default browser with no issues now for at least 6-8 years, suddenly within the past 90 days I am being signed out of Firefox without my knowledge or consent almost every day. Thus, websites are not recognizing me that always did prior to these issues (Facebook, Amazon, local grocery store chains, etc.) and I am having to go thru full security log in procedures over and over again, day after day. In the past I NEVER had these issues unless I ran a CC Cleaner scan or other PC clean-up software and, even then, I would simply go thru the security procedures and sign in to their site or account one time, then would be fine for week/months until I ran a cleaner scan again. What do I need to do to keep myself signed in ongoing with Firefox so that it does not disconnect me every day and I can avoid so much wasted time with all these security measures for my commonly visited sites (incl YouTube)? If this continues I am strongly considering using a different default browser that hopefully can eliminate these very irritating daily issues. Thanks for your help, Jim S.

YouTube videos show up as "video Unavailable".. I can see and talk in the Chat but the video OR Live Stream is shown as "video unavailable".. This only happens in FIREFOX which is my main browser. Now if I sign out, I can watch the Live Stream OR video, but CAN NOT use the Chat, IF I am SIGNED IN, I CAN use chat BUT not see the video.

I am now using (which I hate using)Microsoft Edge to see the video and chat. I WOULD LIKE to be able to use FIREFOX again! Please Help
