Firefox Community Forum

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.

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes and a force quit is necessary.

12 hours ago Firefox stopped working .No reason ; no changes just the following message including access to this site.So now I have to access with edge . Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Since the last few days weather.com will not work with my version of Firefox. I use 115.37.0esr version of Firefox. Since the last few days Weather.com seems like it is loading and displays the page correctly for half a second but as soon as the page appears, it disappears leaving a small message midscreen that says " This page couldn’t load - Reload to try again, or go back."

I tried turning off my adblocker but that made no difference. Anyone got any ideas? I really like weather.com. It's one of those nice websites that are like when the web was new and was just a useful thing for everyone.

I have just been on the phone with my bank after arguing with their bot!

I was having trouble on their website, so they gave me some instructions over issues I was having on their website. I followed their instructions, but the changes I made were not registered. Suddenly, a message came up on my screen from the bank telling me that my firefox is not up to date, as it was only on version 152.0. I then checked to find that Firefox has just released an update to version 152.1.

Thinking that this should not really affect my connections with my bank, I looked up this forum to find that other users have had similar problems, and when investigated, it was the banks IT departments that have been too lazy to adjust their systems to Firefox updates. I also noted that last evening we were having buffering problems on our tv, which may or not have anything to do with the update, although I read from Mozilla Support that this too can happen.

Could you please confirm that this is our problem, and that it will soon correct itself. If not, could you please let us know if there are measures being to prevent this in the near future, as although the tv is not important, it has been a little stressful having to make important transactions with the bank.

I ask this with respect, knowing full well that you have provided me with many years of an excellent free service!

Since the latest version (152.0), right clicking on a file link, select Save As... and with the popup with the filename and saving location being OK just hitting <Enter> doesn't do anything anymore. I now have to specifically click the "Save" button (or use <Alt>+S) to get my file saved. This is highly annoying as my muscle memory gets in the way all the time. Please get the original behavior back. Just found out the same behavior is with file upload.

I had my desktop computer set up so that al the text was bigger on every page website and I had a contrast theme set up that worked for my vision. But today there was an update, and now I cannot read anything in any of the tabs in the navigation bar. I also can't read any of the text in any dropdown menus for the tabs. It did not effect the size of type of web pages, but it is causing me real problems with navigation. How can I fix this?

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.

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.
