Firefox Community Forum

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

I am on a web page and right click & select "View Page Source" that then opens in a NEW TAB with the source code. Then CTL F and select the string "mp3" to find. This then takes me to a position 142 characters to the right of the actual "mp3" location. Skipping back to actual location the "mp3" now appears as "blank". Very strange!!

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?

For tab settings I have checked these: Open links in tabs instead of new windows When you open a link, image or media in a new tab, switch to it immediately

In the past links opened in new tab immediately. But now some links open in SAME tab immediately. For example: I open https://www.pbs.org/livestream/ and start watching the livestream. When I click the link On Air Schedule It opens immediately in the same tab, which ends my livestream

Доброе время суток!

это папка C:\Users\Илья\AppData\Roaming\Mozilla\Firefox\Profiles\v2zudvil.default-release\storage\to-be-removed постоянно растет, удалять ее приходится вручную, почему так происходит? и как это избежать 

последний раз, когда удалял, это папка занимала 52ГБ

When I open one tab on Firefox, my task manager shows multiple programs running along side it. I know some extra processes are needed but this seems like an unusual amount. I have included a screenshot of the tasks that appear. When I try to delete these, they reappear. I have tried various online solutions such as uninstalling and reinstalling, and checking various settings. It is affecting my computer's performance and I am not sure how to solve this. Thank you!

For about a year I have, several times, tried to use a link or a pop up that doesn't work in Firefox but can be accomplished in Safari. Today, I used a credit card to pay for something on the UFT.org website. It worked. I needed to make another purchase on the same website and page but I got a message that there was an error with my credit card info. I tried again. I tried another credit card. I signed out and back in and repeated everything and still got the same message. I copied the url, went to Safari, pasted the url, entered my info and was successful in making the payment. I am using Firefox 133.0.3. What might be happening to cause these problems?

Still waiting for an answer to the above question. Why does the page jump back to the top when I want to open a link in a new tab? The link is halfway down a page but when I do a right/left click it jumps and invariably opens the link a few articles above the actual article I want to read. This had been happening for months now and nobody has bother to give a solution.

I want links that I open (in Firefox, from Firefox, like opening any normal link) to open in the same tab (unless otherwise specific, like a normal browser should work), and all links from other applications to open in a new tab.

Whenever I click a link, it overrides my current tab, even if I'm working on something important. Apps do not always make it obvious what might be a URL. Windows for instance LOVES to open up "support" links in your browser. Firefox also does this itself with its update function, it opens up its update notification by overwriting your previous tab.

This is a really, really basic feature that should really be a default setting, but it doesn't seem to exist in settings at all.

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

Help me return to correct settings in Firefox so I can enjoy playing "June's Journey" and "Pearl's Peril"(which isn't opening). As I explained in my question, there's a wide band across top of "JJ" game which appeared, as well.

 About one week ago, I was trying to re-set use of my debit card, was unable to as I'd probably severely cancelled it 6 months ago. I don't have a clue as to what the connection between these two activities have to do with each other but it's all I have to go on.

Thank you for any help! I've asked Wooga to give me some steps; I tried following them but Pearl Problems continue to plague me.

Recently, the Firefox browser stopped working. Specifically for me, Costco's website, and Aetna. I believe the issue could be that those websites require that the location is confirmed, but no pop is generated, thus causing the website to not work with Firefox. Please help me, as your browser is the best.

This is something I've noticed in the last couple of mouths...

Initially everything on Firefox runs fine for the first 1-3 hours, but after that the multiple YouTube website video tabs I generally have open, especially the very last YouTube website video tab that's open, or any new YouTube website video tab I open, starts to lag like crazy.

Using my mouse to click the play/pause on the video player, or pressing the play/pause function key or spacebar on my keyboard, takes a good 3 or 4 seconds before the input action is registered, and it's not just that but the entire UI of the web page itself is slowed down.

Doing simple things like clicking on-screen buttons to navigate, and scrolling down to load comments, or scrolling down to load other video thumbnails etc etc, takes a good few seconds to actually work.

In general the YouTube tab(s) become very slow and unresponsive, and it's not just the video player on the tabs - it's the YouTube website in general that is affected.

I don't see a substantial difference in CPU or RAM in Task Manager when these 'slow downs' occur, but the fan speeds inside my mini PC do spin louder and louder.

For whatever reason this problem ONLY happens with YouTube. Other websites via other tabs tend to run and function just fine 24/7.

I'm running the latest 133.0.3 version of Firefox, and my system specs are as follows:

Processor: Intel(R) Core(TM) i7-10700T CPU @ 2.00GHz Storage: 595.2 GB Installed RAM: 16 GB (15.7 GB usable)

Other people have also reported similar things over on Reddit with regards to Firefox and YouTube.

For several weeks now, I have been unable to upload videos to a group in Facebook using Firefox. Previously, I posted a video almost daily. The loading wheel keeps spinning. This in Windows 11 Pro version 24H2 with Firefox 135.0 (64 bits).
