Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

This morning Firefox stopped working for every website I attempted to access. The window shows the "Unable to connect" error. I'm currently using Edge for the Mozilla site help pages. I've tried many of the help article procedures, including: 1) Removed and re-added Firefox in the Windows Defender Firewall settings; 2) Scanned PC for Malware (Webroot SecureAnywhere, CE25.1), no threats detected; 3) Cleared recent history from Firefox. 4) Opened Firefox in Troubleshooting Mode but the problem persists. 5) I've also set the Network settings to "no proxy". Windows settings is set to automatically detect settings Firefox was working last night when I was installing an old version of Quicken 2015 (off-line/non-network installation). What's my next step?

White (blank) screen on some (but not all) websites

For the past month or so, I'd say about 20% of the websites I visit using Firefox just show a blank, white screen. (See allbirds.com site image attached for example.) … (read more)

For the past month or so, I'd say about 20% of the websites I visit using Firefox just show a blank, white screen. (See allbirds.com site image attached for example.)

1. Cleared the cache and cookies to see if that fixed it. It didn't. 2. Entered Troubleshoot Mode to see if that fixed it. It didn't. 3. Disabled all extensions to see if that fixed it. It didn't. 4. Disabled "recommended performance settings" and hardware acceleration--in combination with some of the above--to see if that fixed it. It didn't. 5. Reinstalled Firefox to see if that fixed it. It didn't. 6. Also paused/disabled VPN (Nord) and anti-virus (McAfee) to see if that made a difference. It didn't.

Any other ideas?

Thanks.

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

Firefox using huge amounts of RAM/crashing

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

I found old posts about this from 2012 or so, but nothing for current version of Firefox I have been using Firefox for years. This has suddenly started happening on my laptop. Annoyingly it also displays the same configuration pop-up with various screens you have to go through, clicking Skip this step before you can start browsing. I reset the Home Page to my preference. But next time I start Firefox it reverts to the Welcome and forgets all settings.

I'm getting really tired of having to reset passwords for Firefox. Mozilla and Yahoo.

Why does that keep happening? I end up getting kicked out for 24 hours. It's very frustrating.

I am currently using the latest version of Firefox for Apple iPhone.

When I tried to close all tabs, it does not close. I click on the trashcan and click to close all tabs, and it pauses for a very long period of time and still retains all old tabs. The only way to close tabs is to go through them manually delete them one by one. Obviously this is not acceptable.

I’ve been very happy with Firefox in the past, and I would hate to Have to change browser platforms, but this is getting to the point where I need to change browsers if this is not fixed soon.

please let me know if this is something I’m doing wrong on my end or if this is a known issue and you have a solution. 

Thank you!
