Firefox149开始，网页看抖音，每滑到下一条就卡顿2，3秒，换回148及之前的版本就没这问题 Starting from Firefox 149, when watching Tiktok videos on the web, there is a lag of 2-3 seconds every time I swipe to the next item. Switching back to versions 148 and earlier does not have this issue， https://www.douyin.com/

Version 148 is very slow. When there are 5-10 downloads, other websites won't open. That's why I use version 140. And why are there so many files in the folder - ....profile\storage\permanent\chrome

I have Firefox running on 3 machines, only one of them is synced to my Firefox account, so that means that I am not running the same addons on all of them. I have Firefox running on Windows 10 and the two other are running on Windows 11. From time to time, I notice that Firefox is running slow and its unable to open normal websites like facebook, instagram, youtube, or any other website that I normally browse, and when I check the Task Manager I can notice one unusual exe running named "crashhelper.exe" which is located in the Firefox installation directory and its signed by Mozilla. Once I kill this task Firefox continues working as nothing happened. This is happening since the last update which was few weeks ago (if I remember correctly). What is this app doing and why it is making Firefox stop opening websites?

So I've got 6 tabs open in Firefox, all working properly. To help me focus on another task, I open a 2nd window in Firefox. It is, however, blank and unresponsive, doesn't show any extensions in the toolbar, but does show "Firefox View" which I don't normally have showing. I can only close the new window by using Task Manager to shut Firefox down completely or by right-clicking in the Taskbar on the dead window and selecting "close window". What's going on here? First image: working tabs, Second image: unresponsive new window. Regards, Ian Firefox 140.0b2 (64-bit) Windows 10 Pro

So, I was downloading some Patreon stuff and Patreon isnt well optimized for browsing older posts. When you have to load multiple more pages dating backwards it slows down the Firefox quite a lot, pretty much to the point when the Firefox reach non-responding state in worst cases.

But luckily for me Patreon worked fine for me tonight, just when I was closing the Firefox, it took like 5 seconds for it to close.

I spent some short time by responding messages on Steam and Discord and then I started new Firefox window, this time I went on Netflix and when the page loaded my monitor went black and then after like few seconds it returned back with "Displayport" message on the top left corner.

When I checked Event viewer, there is nothing at all. When I checked about:crashes, there is also nothing.

Any idea what was that and how to prevent that?

Bug Report for Mozilla Team: When you open a Gmail PDF In another window, the zoom setting has a bad response, with much delay, I inform you of this Bug So you can fix it, thank you very much.

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.

About two weeks ago, Firefox started randomly hanging and would stop responding. It wouldn't let me close the program and I always have to restart my system to resolve the problem. Sometimes it only takes a few minutes after restart before it hangs, other times it will be fine for hours.

I've tried multiple solutions I've found online, carefully following instructions: clearing cookies and cache, disabling all extensions, refreshing firefox, creating a new profile, deleting specific files within the Profiles folder, etc.

I've yet to make it more than four hours without the program hanging.

Any assistance or suggestions are greatly appreciated.

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...

Firefox occasionally stalls during a page load or refresh. A quit/start sequence of Firefox resolves the stall without further action. Is there a key sequence that invokes a restart: Firefox 140.0.2 (aarch64), MacOS 15.5 (24F74)

Several weeks ago Firefox worked normally for me. I left for most of the day and when I got home Firefox no longer worked at all. Everything on my home page was gone and when I typed in websites - such as my e-mail program or Facebook, nothing ever came up. I'm not super browser savvy, but I opened the menu and under help was "trouble shooting mode". I didn't know what that was but figured nothing much more could go wrong with Firefox, so I chose that. I had to rebuild the websites I had in a row on the middle of the page. I didn't lose bookmarks, but everything else was different. So I left it that way.

Earlier today, Firefox wanted me to do another update. I thought maybe by agreeing to that, things might return to normal. Noooooooo. It's no better whatever. Now I don't know how to get out of troubleshooting mode to know if anything will work normally again.

I am seriously considering switching browsers, but I have a LOT of stuff bookmarked and that would be very intensive to build all those book marks in another browser.
