Firefox 技術支援討論區

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

suddenly Firefox is blocking my entry to a specific site with the measage "Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have tried umpteen ways around this to no avail. Google Chrome does not have this problem!! I am using version 100.0.2

I think it has to do with cookies, but I can't figure out what to fix. I have my tracking privacy set to strict. Twitch has permission to use my cookies and site data (Settings -> Privacy and Security -> Cookies and Site Data -> Manage Exceptions). All of the other websites that I have granted that permission to have no problem remembering my device, but Twitch does. I looked at this post already and my account was already set to these settings. How do I make Twitch remember by device? It's annoying to have to go to my email and use a one-time passcode every time I log in.

Hi, I love my recommended by pocket on my new tab or when firefox opens. Yesterday Firefox asked me if I'd like to try a new setting disabling all cookies, I did opt in. After that my recommended by pocket disappeared. I opted out of disabling all cookies, but it hasn't reappeared. I checked about:config and the setting for recommendations is true. Please help!

I watch videos on dropout.tv which uses the Vimeo SDK as their player for the videos. After switching to Firefox, the video progress has consistently started from where I left off on Chrome. The site doesn't remember where I ended the video when I watch it on Firefox. I assume this has to do with the cookies, but I've manually added "dropout.tv" to the list of exceptions in Firefox settings so that that site is always allowed to store cookies.

Returning briefly to Chrome, the player immediately tracked my progress again, so the issue is definitely related to Firefox somehow.

I keep getting a message that "CAD 3.8.1" has deleted my cookies. I get this message every few seconds. I can't find where it's coming from to disable it. As a result my log in info isn't saved and I have to keep logging in. Has anyone else had this problem?

I use CCleaner>Options>Cookies to save cookies in certain containers. I see that Firefox uses userContextId to specify a container. Where can I find which userContextId NUMBER is assigned to which container NAME?

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

i've been a loyal fan for over 20 years but i just can't comprehend why would ignoring dns settings be a good idea .. i can't even imagine a hypothetical situation when this makes sense.

and now i have to either tolerate edge, chrome or just forget internet which is really hard to do when you work in IT ...

amazing.

Hello,

I am having problems with some sites and the error seems to indicate that it is related to cookies.

In Google Drive, when I am trying to download any file, it is getting stuck in some kind of loop and at the end, it is showing this:

The page isn’t redirecting properly

An error occurred during a connection to drive.google.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

Apart from this, when I am trying to log into my Riot account in Valorant's website, it is ending up showing this:

Expected redirect cookie to exist

I have tried following:

• Using Standard mode for tracking protection
• Disabling tracking protection for these sites
• Deleting Cookies & Cache
• Reinstalling Firefox :(

It didn't help. Also, it started after I reinstalled Windows 11. I have yet to setup it, so I have not made any changes.

Also, everything is working fine in other browsers.
