I received the error message that Firefox could not open because it was already running, but this did not show on the task manager. I googled the issue and stumbled upon a solution where people had deleted their profile in order to solve it. So I did, and Firefox worked again, but all of my passwords, bookmarks and everything was lost. Is it possible to recover this?

I am using a Mac.

Mind you, I am super bad at technicalities and would probably need explanations as if I am five years old.

I am using Firefox 84.0.2 Around mid day today, I started having problems viewing my Google Calendar on Firefox. As"skeleton" calendar page loads with no dates or details. Coincidentally, it would not load on Firefox on our main PC either. I have cleared history, cookies, etc and tried changing security settings, but it will still not work. It works fine on Edge and my Android phone. Any advice would be much appreciated. Thanks.

I recently migrated all of my files and applications from a 2013 macbook retina pro that had FF 56.0.2 to a 2020 macbook retina pro. The application transferred over with no problems with one exception. I have a blog on livejournal.com and now cannot post or reply to comments on the blog. FF just hangs and freezes. I can't even quit the page unless I quit FF totally and then restart. I can still access livejournal from Safari w/no problems. I checked my extensions (only have two) and disabled hardware acceleration but nothing has helped. Does anyone have any suggestion? I'm not crazy about safari and would like to continue to use FF. Thanks so much for any help!

I have refreshed my Firefox, because it was slow.

In the description was written: Firefox will save these items:

   Bookmarks
   Browsing and download history
   Passwords
   Cookies
   Web form auto-fill information
   Personal dictionary 

Ok. It's fine. But after refreshing the Firefox how can I restore these elements?

Please send me a step by step instruction, without referring the webpage, because I have read it and it is not clear for me.

Where is my older profile? Where is my new profile? How can I move the elements from the older profile to the new profile?

Thanks a lot: Mihaly

Version 84.0.2. Windows 10. I inadvertently opened a second FF window which had no tabs and no bookmarks toolbar. I closed FF which had many open tabs and many bookmarks toolbar items. Now all tabs are lost and all toolbar entries are lost. On reopening FF, only the FF with no tabs and no bookmarks toolbar will open. I have searched and read many "solutions", but nothing that I can get to work. Does anybody actually know what can be done or that nothing can be done. I had not yet reinstalled my general backup program prior to this so there is no other backup and all I have to rely on is FF alone. Are at least the bookmarks toolbar items stored somewhere even if the tabs are not recoverable?

All bookmarks are there except for bookmarks toolbar items.

I would like to restore both tabs and the bookmarks toolbar if possible. If anything can be done, can anyone articulate some clear instructions?

As captured in the long thread "What's the difference between ALLOW and ALLOW for a SESSION?”, with a lot of handholding from jscher2000, I managed to set custom choices for privacy and security the way I wanted on my mac computer (blocking all cookies in all windows, with exceptions saved for ALLOW, ALLOW for SESSION and some for BLOCK). To accomplish this, required enabling deletion of cookies when Firefox closes.

My assumption based on information I got in the above mentioned thread, was that even when deletion of cookies is checked for when Firefox is closed, cookies for websites identified as exceptions with ALLOWED, are not deleted.

However, this is not what happens. A specific example is tripcheck.com, which stores custom itineraries for cameras in cookies. I setup quite a few of these custom itineraries and saved them and they were OK until I closed Firefox, when they were deleted, as the cookie was deleted. This website is setup as ALLOW in the Exceptions list.

As explained in the above mentioned thread:

"(2) Scenario Two

[X] Delete cookies and site data when Firefox is closed (checked)

Firefox shortens cookie expiration to session only unless the site has an ALLOW permission in the exceptions list. “.

I am more confused than ever, the settings do not appear to be working the way they are meant to work, not only for session cookies but also for what should be "permanent".

Am I doing something incorrectly or am I misunderstanding how setting should work?

If cookies of websites setup for ALLOW are deleted when Firefox is closed, the setting is defeating what I am trying to accomplish: saving cookies for websites that I use and save data in cookies (such as recognizing the computer, what’s needed for 2 step authentication, etc.).

Thanks.

I've had this happen twice now. Getting a new PC and wanting to transfer my bookmarks from old to new. I have had bookmarks on the old computer arranged in order of priority from left to right on my bookmarks bar. Did the export to create a HTML file and saved it so that I could import to new Firefox browser on new computer. So far so good. However, when setting up new browser and importing my bookmarks from the HTML file, it just creates a single folder on the new browser's bookmarks bar, instead of spreading my bookmarks out on the new bookmarks bar as it should. The bookmarks in the imported folder are still in the order I want, but to get them as individual items on the bookmarks bar, it seems I'd have to drag and drop them one by one to the new bookmarks bar. Solution please?

  1. Ubuntu garbage data increases exponentially
    1. Intro and context

Hello. I am a power user that works in software and web development. I have been using Firefox on and on for most my life, but full time as my main browser since late 2018. One thing I love Firefox for is its lightness on memory compared to that of Google Chrome, and also its open web standards, open source, privacy, ethical owners, and customizations. I have been using Windows 10 up until July 9th 2020 before I switched to my first main Linux desktop. I have always kept my eye on CPU and RAM usage, as high CPU drains battery and running out of RAM results in a system crash. I actively keep many tabs open (less than 100 but more than 60) I ensure that they are light. I mostly have GitHub tabs open, but I keep a few other things open as well, mostly Wikipedia/wiktionary and duckduckgo tabs, a pcloud (file service) tab, but sometimes a youtube tab or two (rarely a reddit tab)

    1. Issue

I have been noting that garbage collection is getting exponentially worse over time. When I got my laptop, I was able to keep 2-3 fully packed profiles open at all times, and never having to close Firefox until shutdown (after about 12-16 hours uptime) I rely heavily on Firefox profiles for organization. It has been getting exponentially worse. Starting in late 2020, I had to reduce the max number of open profiles to 2, and in 2021. In early January, I had to start closing the profiles once a day to free up 2-3+ GiB of RAM (swap doesn't change much, that is the garbage data that isn't being cleared, it normally ends up at 800 MiB to 1.7 GiB by the end of the day) and now (as of January 22nd 2021) I have to close Firefox 2-3 times a day to prevent my system from getting overloaded, as Firefox eats through 1-2 gigabytes of RAM per hour, even when idle. I have noticed several processes titled `web content` that use 200-600 MiB each (there is usually 2-7 of them) I am wondering what I can do for Firefox to prevent high RAM usage. For reference, here is my main profile in idle mode:

Mozilla is refusing to let me upload images right now, so I will link them

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/MProfile1_Idle_1.22.2021.png

Here is my usual 2nd profile in idle mode:

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/MProfile2_Idle_1.22.2021.png

Here is the RAM and SWAP usage before my 2nd refresh today (uptime: 8 hours 46 minutes)

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/FF_GF_Open_1.22.2021.png

And here it is with Firefox and Nautilus closed (I forgot about nautilus before getting the first 2 pics, it uses a lot of memory depending on its usage):

https://github.com/seanpm2001/seanpm2001/blob/master/FFTechSupport/Jan22/FF_GF_Closed_1.22.2021.png

I have lately suspected that GitHub may have gotten heavier, or is sending too much data via AJAX methods, but I am not entirely sure.

    1. System specs

Device: `Dell XPS 13 9XXX`

Operating system: `Ubuntu 20.04 (Focal Fossa)`

Linux Kernel version: `5.4.0-48-generic`

Processor type: `Intel Core i5 10th generation`

Processor specs: `Intel® Core™ i5-1035G1 CPU @ 1.00GHz × 8`

Processor mode: `x64`

Desktop environment: `GNOME 3.36.1`

Windowing system: `X Desktop environment 11`

Memory: `7.4 GiB (8 GB)`

SWAP file: `2.0 GiB`

Firefox version: `84.0.1` - I haven't updated in a while due to fear of memory increase and instability

Number of Firefox profiles: `61` - no new profiles created since December 26th 2020

I am wondering what I should do about this. I work with hundreds of projects, so I can't close too many tabs, as it becomes hard to access and manage. I intend to close 16 tabs in the next month, as I am freeing up some projects.

However, upon saving or printing, the text gets rendered with a massive font size nullifying the ability to edit in browser. I've been trying to find some online resources without success, and can't seem to find others reporting a similar case.

I've disabled all extensions and restarted Firefox, but did not notice any change in behavior. Any tips for debugging? Attached are two pics of the PDF form while editing, and then the rendered PDF after saving.

Firefox 84.0.2 (64-bit) Running HTTPS Everywhere Running Privacy Badger Firefox set for standard enhanced tracking protection HTTPS-ONLY mode set for all windows

At my bank and a few other websites using HTTPS as standard operating procedure, Firefox gives me an error that the site is NOT using HTTPS and gives me the option of using only HTTP! This is unacceptable, financial transactions must be secured with HTTPS. What is the fix for this?

I'm spread thin and don't have the personal time resource to keep hunting through thousands of miscellaneous support articles that, from their titles, I haven't a clue whether they are relevant or not! (Though I tried investing an hour or so in this exercise getting nowhere.)

Sorry, I didn't save copies of the same error message on three different HTTPS sites.
