Firefox Community Forum

Updated to Firefox 152.0.1 and I've noticed about:privatebrowsing now has a very bright garish (subjective) purple background; I'd like to replace this with something else.

Here's what I've tried so far:

• Adding the css in this 2023 reddit post to my userchrome.css
• Fiddling with about:config, per Ty and James' replies in this similar 2022 question
• As a sanity check, directly editing the style element of the body tag in the inspector to check if `background-color: #424242` the css works. (obviously doesn't stick, see first point)
• As a second sanity check, changing the colour in the userchrome.css to fuchsia, as I'd read in older articles there'd sometimes be a flash of colour before something else was applied and bright pink is easier to see than grey
• Changing the Firefox theme from System theme (Auto) to Dark, Light, and then Firefox Alpenglow to see if that would change the background colour (it doesn't).

I do see that Alpenglow theme now matches about:privatebrowsing shockingly well, but it's not my preferred flavour of utilitarian blacks/dark greys.

Tried to show what I'm after, screenshot of about:privatebrowsing in a split view next to about:newtab. Other than above, the only other things in my userchrome.css are some styles to attempt to return curvy tabs edges.

Good morning from the UK. When I loaded my laptop this morning there was a message saying I need another firefox, I get worried quickly and didnt take a screen shot .

I am on windows 10.

I have notice that the laptop is very slow on loading everything.

Please help me and advise...I'm not computer savvy sadly.

Thank you Barbara

I came to know about Firefox Widgets but can't see any on Firefox 152 on Windows 11 desktop. The option Allow Firefox to improve features, performance and stability between updates is already checked (Screenshot attached) as suggested by users.

Those instructions don't work and I'm sick of spending so much time on this problem these days.

Now thinking it happens after an update, which is a problem because they seem to come just days apart. None of the solutions offered works because right-clicking on the top doesn't do anything. Nor does going into the settings in the app on my laptop or online. I've downloaded and installed the latest version of Firefox more than once in the recent past. I've also shut down my laptop and rebooted. Nothing works. It's extremely annoying not to be able to access the features that I use *all the time*! day. I'm using a laptop with updated Windows 11.

Tab group name's width get maximized after dragging it to other place. Please refer to the third tab group from the image. If I restart the browser, the width become normal until I drag n drop it again.

I am so excited to use the FF VPN, I get many notifications about it but what am I doing wrong - I don't see the VPN option in my browser. I am updated, use DuckDuckgo for searching. I've written before but we never go anywhere. Wish I could get the VPN to work as I really want to try it thank you

My Firefox is set to auto-update and did so Wednesday night, so it's currently 152.0.1 (64-bit). Since then, it’s been virtually unusable on my home computer (a 2017 iMac Intel Core i5 running Ventura 13.7.8).

I’ve changed nothing about the way I browse, yet having multiple tabs open at a time makes the application either non-responsive and I have to force quit or makes it crash (from today: bp-3c95c176-fde2-40e4-a61c-c5c080260619 bp-7ebe2fc9-0be2-4db2-b0e3-675df0260619 bp-bfe86698-eaf0-4cd2-96c3-ed20b0260619

It crashed four times yesterday as well, but I inadvertently submitted ALL previously un-submitted crashes, so I'd have to dig through to find ones from June 18th).

I can't get most websites to load. I cleared all my browsing data this afternoon in the hopes that it would help, but now I'm having trouble logging into sites like Facebook, Instagram, etc.

Videos on any platform will not load, let alone play. Instagram, YouTube, Peacock (which I think was having an outage last night), Twitter, BlueSky, etc. YouTube BRIEFLY loaded and played a video last night but there was no audio. I tried searching a word’s pronunciation in Google, no audio. It will not play audio on any music sites (SoundCloud and Bandcamp; they both show that the music is playing, but the indicator bars do not move on either site, and again, no audio).

I believe this is an update issue because work computer (MacBook Air, 2017 running Monterey 12.7.6) is using Firefox 151.0.1 and everything is working as normal there (fortunately I leave Firefox open all the time on that computer so it hasn't auto-updated). It had also been running fine BEFORE the update.

Any ideas on a fix?

When I log in to any forum, The address bar and the return circle with the clockwise arrow goes crazy and blinks off and on rapidly. All other sites work normal. I modified nothing. Yesterday it just kept on happening. Both computers are doing the same thing. Lenovo P520 Servers. The only way I can stop it is to kill the current tab.

After updating to Firefox 152.0.1 this morning I keep getting Error 7023 Service Control Manager each time I start Firefox. The error description states "The MozillaMaintenance service terminated with the following error: Incorrect function." The Mozilla Maintenance Service was set to Manual and I set it to Automatic but still getting error each time I start Firefox. I have read that the service can be disabled so what do you suggest I do to stop the 7023 error. Thank you.

Why i can't login to https://laboutik.com.br/login anymore? was working well before.

- The login page show up - When click for conection, the window close directly and it comes back to the Firefox home page.

Firefox has been laggy at times lately on my PC (Windows 11 Home, Firefox 152). I have tried some fixes with no success (clearing the cache, deleting YouTube cookies, using the User-Agent Switcher, etc.) Other browsers appear to be unaffected. I first noticed this on YouTube, but it seems that other websites are affected as well.

I am using a Wacom tablet as a touchpad for my PC.

And its scrolling functionality works perfectly fine in every program except on YouTube, specifically when a video is playing.

All of a sudden, scrolling up or down now also registers as a horizontal scroll and skips the video timeline back and forth.

Tried disabling all I could think of related to gestures, horizontal scrolling, or smooth scrolling in the about:config page, but nothing worked.

Disabling the vertical scroll action in the tablet's software does disable vertical scrolling in Firefox as well, as expected. So, changes are getting applied. However, not so for left/right gestures, disabling those in the software had no impact whatsoever in Firefox (on YouTube videos).

Finally, this issue does not occur on Chrome at all. Chrome can handle vertical scrolling on YouTube videos just fine with no need to disable anything.

So, hardware wise, everything is working fine.

Is there any solution to this?

I am perfectly fine disabling any horizontal scrolling gesture whatsoever if that turns out to be the solution.

Thank you!

My I Mac is old 2014. Recently, I seem to get the spinning ball of death every time I try to load a page or even try to close a page. Articles take a long time to load, too. I am not the computer tech knowledgeable but the other day I found myself yelling at the computer because it was so frustrating trying to do anything.

I suppose it could be time for a new piece of equipment but that is not cost effective at this time.
