Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

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.

Even though I have removed the cookies for Facebook, the Manage Cookies screen shows a HUGE storage space. FF v99.0 on Mac

==

from preferences page: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space.

==

almost all are Facebook storage. I'm feeling a little reluctant to delete all site data. If I clear all cookies and site data will that fix the issue? will the issue re-occur?

Regardless of what I have tried i still have:

Cookies and Site Data Your stored cookies, site data, and cache are currently using 218 kB of disk space.

Iam using: History Firefox will Firefox will remember your browsing, download, form, and search history. Always use private browsing mode

Firefox is u to date I have restarted ....

Thank you for help - Nicolas

I keep getting this prompt: "It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve this issue, please update your settings to allow 3rd party cookies." I have tried so many things and nothing is working. I've had this happen before sometimes at the beginning of a semester; but I have been able to restore it in the past. Now, nothing I do works. Please help. Also, how can we prevent this from happening again? Kaltura is a well known website used by colleges and universities for teaching online classes and playing back video. Why do we have to constantly update the settings? And if so, why are they not working now? Please help. I need to teach my class. Thanks.

So I updated today as requested and now all the sites I had previously checked to allow pop ups etc on are no longer functioning.

Why dod you not include copying these settings in your update,

What a massive waste of my time

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 have a constant problem with Chase.com - they are telling me it's Firefox, then it's because of the cookie blockers on FireFox. I have heard every excuse under the sun. I try to login, I get chase doesn't recognize device, then they send a one time code, which doesn't work, so I have to call them, they tell me it's Firefox causing the problem. I know that's a myth because the same thing happens on MS Edge. Is anyone else having this problem? Do you have any suggestions?

I manually delete cookies at the end of the day, and after the latest update it shows 13.0kb left after deleting. I have no exceptions or any other setting other than to delete ALL cookies. I can not find what this 13.0kb is and why is it still there after deletion? Windows 10.

I have tried EVERY suggested fix for viewing Kaltura videos in the FireFox browser. NOTHING works! I refuse to use Google (they know enough about everyone as it is) and Edge works but I do not care for it.

Can't be that freakin hard to allow the viewing of Kaltura lecture videos posted by professors in an application that is used by many educational institutions across the country. Google and Edge seem to have figured it out so why can't Mozilla?

This issue needs to be fixed!

I have Firefox 99 for Mac "Delete cookies and site data when Firefox is closed" is unchecked History is set to "Remember History" Enhanced Tracking Protection is set to "standard"

Yet every time I return to a site where I've checked "remember me" , I'll get prompted to login, and perhaps also get a security message "you've logged in from a new computer" in my email from the site.

Is there an easy way to verify that Firefox is storing cookies for a site. Maybe an option to right-click on a site's web page and view "cookies are stored for this site" in the context menu? I'm losing a lot of my productivity time logging back into sites that I just logged into earlier in the day.

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!

Hi, I'm trying to clear my cache and site data (in order to update my gmail signature), and each time I clear selected sites - namely gmail which had hundreds of thousands of GB cached - it just comes back. After tyring this 4-5 times, Youtube started having hundred of thousands of GB cached too!! So now, despite managing data an clearing these repeatedly, there's more than when I started. I think I'm stuck in a loop somewhere, please help! thanks in advance

I'm using Firefox 99.0.1 on a Macbook Air Mac OS x 10.15

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 clicked on 'block cookies' option( never seen this before but I trust you guys so....) when I logged onto firefox this morning, since then there are various apps I cannot get on to, eg Twitter, my banking through Nationwide, very frsutrating. So I tried to set a restore point prior to thios morning but that made no dofference, getting desperate now.
