I have used Thunderbird for almost 20 years and I love it. I have not had basically any problems with it until this fall when I started to direct my gmails through it too. Before that, I only directed the emails from my university's server.

My computer's OS (C:) memory started to run out. The Storage claimes that my Apps & Features tool 189 GB although I did not have a lot of different kinds of programs there. I just found out that the reason is the hidden files under Users/...../AppData Properties/Roaming/Thunderbird/Profiles/..../ImapMail/imap.gmail.com/[Gmail].sbd takes 143 GB!!!

I do not understand how this is possible and how to solve this problem. Can I safely remove the folders under [Gmail].sbd? If not, how to solve this problem? My computer is soon dysfunctional because the OS memory is running out.

Thank you for your help.

Firefox seems to be a very high user of disc resources. I can hear the drive it's installed on being continuously accessed, and can see in Task Manager it's almost always using the most disc resources of any process. Even with one or a few tabs open, when Firefox isn't being actively used.

Can anyone tell me what is going on, and most importantly if there is a way to reduce the endless disc access. thx,

I am using the ESR versions of Firefox and would really like to have the clients auto-update as soon as possible but I still want to test new major releases when the come available. Now I know I can use the early releases to test but that pins me down because then I need to be done testing before the public release comes out. So I am looking for an option to install auto-install all minor updates within the same major version but not auto-update to a new major version. Is something like this possible or where can I find this setting?

Each time I close the browser, firefox deletes all log in data. When booting the browser, I need to log in wiht username and password for all software. How can I stop that from happening and continue using firefox always reusing previous log in data?

For more than 10 years I have commented on many blogs, some nearly every week, however for the last several months every attempt to comment has produced the message

"Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

The browser prevented this page from loading in this way because the page has a content security policy that disallows it"

This happens whether I am using laptop with Windows 10 and Firefox or tablet with Firefox for Android, using a Google profile

Hi, i found a Problem with the Nvidia Website https://www.nvidia.de/Download/index.aspx?lang=de

When i Search for Driver Download, i choose "Producttype" and then when choosing "Product Series" the Website allways Resets to Start.

I also Informed Nvidia about the Problem, but it is only on Firefox. Im on Linux (Ubuntu 18.04) and use Firefox in Latest Version 83.0 no addons.

I also Try Chromium and other Browsers but this Problem only happens on Firefox.

My wife called me in this afternoon when big red error message popped up "saying" it is a red alert and the web page used Apple's logo on it, said the old 2011 iMac, OS 10.10.5 Yosemite, is "blocked" and has a virus. It had an 877 phone number to call but we failed to write it down. She did nothing after that. When I saw that I pressed the red window page kill button, upper left. Got the rotating rainbow ball. . . computer working overtime. Next, Command-W to kill the webpage, nada. Finally, pressed the hardware ON/OFF button behind left side of screen. On SAFE restart I opened my account not hers and found Firefox had thin, white, flashing lines across the tab bar area(full width) and tabs were flashing individually. Every time you open a tab, this happens or possibly when it is accessing. So, I upgraded Firefox, leaving the OLD version intact. Upgrade I NOW notice is the 64 bit version.

Is there a fix out there? or, is this thing "infected" with the CCP virus or something? Fix for it?

I will shut down and re-open the old version and see if it still happens and post an update here.

Why is my Grammarly not working on Mac? I noticed it wasnt working on the Canvas website and then I uninstalled and reinstalled the grammarly extension and it is still not working. When I click on the toolbar on the green g I get a blank white box. Help!

in my emails is a function called 'mark as'. The drop down menu includes 'block sender' and 'spam'. Block sender only works a small portion of the time. I get a message 'error--can't block sender' Why can't I block a sender I do not want to receive emails from?

I got an error on one of my open or pinned tabs (do not recall which it was). I do not recall what the error was and did not screenshot it because I was sure that closing Firefox and restarting it would fix the issue. I did just that, closed Firefox and reopened it to find that ALL of my pinned and open tabs were GONE. This also happens if another instance of Firefox is opened and I close my main one first by accident and then close the other Firefox instance - ALL TABS LOST.

This is what I have done: • I started to restore the pinned tabs as I could remember what they were but I was not able to remember the open tabs that were not pinned • I searched for lost tabs on the web and on the Mozilla support site but was not able to find any useful help - most of it seems outdated or no long compatible with my version of Firefox. • I looked for the sessionrestore files on my local PC but could not find them - this must have changed in some version of Firefox between version 42 and version 82 that I have. • I looked in the AddOn store to find something that would help restore and prevent this issue - but found nothing. A very old post, from 2012, indicated one that did this but it is no longer available. • All of the Options in Firefox to restore previous session, reopen previous tabs and all that were blank.

This is VERY frustrating in that it results in lots of down time to recreate what was open and is equivalent to working on a document for days or weeks only to find out that the Microsoft file got corrupt or did not save properly.

I am using Firefox version 82.0.2 (64-bit).

Two questions: 1/ Is there any way I can get the pinned and open tabs back from the previous session? 2/ What can I do to avoid this issue EVER happening again.

Thanks!!!!

I like to disable the automatic restore of sessions in all circumstances. I'd prefer to retain my history though.

Using firefox 84.0.2 on Ubuntu 20.04 Whenever I logout/login or restart the OS, FF restores my last session without asking. It's ok when I close FF first (FF starts a new session) but every other app shuts and resumes gracefully.

There are a lot of similar questions suggesting various settings...

browser.sessionhistory.max_entries =0 browser.sessionhistory.max_total_viewers=0 browser.sessionstore.max_resumed_crashes=0 browser.sessionstore.max_tabs_undo=0 browser.sessionstore.max_windows_undo=0 browser.sessionstore.resume_from_crash=false

"Restore previous session" is unset.

None of this solves the problem.

Comments on other post suggest that linux shut down causes FF to crash. Seems that you cannot disable the restore session after crash and I get no "Do you want to...." screen.

Is there no way to tell FF not to restore crashed sessions?

I am trying to serve a print view and redirect the user to the page they came from right after printing (or cancelling). This works fine in Chromium with the following bit of JavaScript code:

  function printPageAndRedirectTo(redirectUrl) {
   window.addEventListener("afterprint", function () {
       window.location.href = redirectUrl;
   });
   window.print();

In Firefox, however, nothing happens at all. Debugging shows that the callback is called, but the href field remains unchanged.

This is mysterious to me. Any ideas what the reason might be?

Firefox version is 84.0.2, Chromium 87.0.4280.88 (both from the Arch Linux repositories).

Edit:

Here's a fiddle to illustrate. Redirect to Wikipedia works in Chromium but not in Firefox: https://jsfiddle.net/xnazLb6p/1/

Edit 2:

Another one to show that the problem here is redirecting from the event listener, not redirecting itself: https://jsfiddle.net/xnazLb6p/2/

I want to understand how and why it happens and mostly how can I stop that to happen again. It's really frustrating that I have to keep my computer on 24/7 so I wouldn't lose anything on here...

I have what I think is a specific video problem. Videos from the Washington Post get the message “This video is currently not available”. Other videos, e.g. from the New York Times do work. Washington Post videos work with Chrome and Opera.

The problem is on a new Dell Inspiron 5502 running Windows 10 and Ubuntu with dual boot. The problem only occurs under Ubuntu 20.04.1 LTS. It does not occur under Windows Firefox.

The current Firefox is 84.0.2. The problem did occur under 84.0 but I didn’t have time to pursue it.

The add-ons manager under extensions has no entries. Under plugins there is only “OpenH264 Video Codec provided by Cisco Systems”.

Under preferences, performance, hardware acceleration is not selected and the content process limit is left at 8.

Running in safe mode does not help.

I had a different video problem on a pair of the hardware visible at https://support.mozilla.org/questions/1320396?utm_campaign=questions-reply&utm_source=notification&utm_medium=email#answer-1381141 This is a different machine and a different problem.

Hello, I am having difficulty opening certain features on certain sites (Openrunner for example) I have been advised to refresh and upgrade Firefox, but it doesn't work. What should I do ? Thank you in advance, Thierry gross

Hi, I am setting up a laptop for my wife to replace her old one. I have installed Firefox and found that although the main body text is the correct size, the text on the toolbars is very small compared to her old one. How can I increase the toolbar font size without altering the main body. Thank you, Andrew

Suddenly ducksuck privacy essentials is running in my firefox install. 1) I don;t want that 2) I was never asked if I wanted that 3) FF downloaded a file without my permission 4) how do I FORBID firefox to download extensions, add-ins, themes or what ever by itself?
