1) Because the built in options are ambiguous I want to flush the temporary Cache storage directory myself, but I can't find it. Where is it? 2) Then I want to relocate it, but here are Mozilla's instructions for how to reset it:

==

To set Firefox's cache folder, first type “about:config” (omit quotes throughout) into the program's address bar and then hit “Enter.” Right-click on any of the displayed properties, select “New” and then select “String” to display the New String dialog box. Enter “browser.cache.disk.parent_directory” into the box and then click “OK” to display the New Value dialog box. Enter the full filepath to the folder you wish to use as the cache folder, and then click “OK.”

==

Doesn't work.

So, after finding the current location and flushing it how do I change it?

My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?

So I've noticed how some video files are able to be played back in Firefox. Some are not able to what so ever, for example I've created a text video using this FFPMEG command: ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 testsrc.mp4

which created the following file: https://astolfo.nl/i/z2ada.mp4 Both the uploaded version and the local .mp4 are unable to be played back in Firefox. However opening them up in edge chromium both files play back perfectly. Besides Edge I've also confirmed it plays back nicely in MPV.

I've tried Hardware acceleration, but both having it on and off did not change the fact that these files wouldn't want to playback in Firefox. Safe mode also did not effect this issue.

On new laptop with Windows 10, with an external monitor in extended desktop mode, Firefox is opening partially off screen such that the top bar is inaccessible so I cannot drag it back on screen. If I close it and reopen, it will usually be back on screen. How can I fix this?

Perhaps related: tabs are not reopened and Restore Previous Session does not work.

There are no extensions open.

Thank you for assistance.

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

  1. Open Firefox
  2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
  3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

  • pulseaudio process should only be spawned when actually playing a media that requires audio
  • pulseaudio should not be the #1 CPU consuming process
  • pulseaudio process should at the very least not massively use CPU when no sound is playing

Hello, I have problems making the sync feature work on my Laptop+Android device. On my laptop, the "synchronize now" feature seems to work, but after ending doesn't actually update my open pages. On my Android device it's even worse, it gets stuck on loading forever and never syncrhonizes anything. I had read that other synchronization features like history, bookmarks etc. might be the problem because they require a lot of time, so I kept them out of my synchronization. Even after that, the problem is still present on both my PC and my Smartphone

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

Several days ago (approximately 12-3-20) my Internet Download Manager add-on stopped working. Removing it and reinstalling it by using a link provided by IDM does not work. It will work only if I open the webpage where I intend to download (e.g.--YouTube) BEFORE I reinstall the add-on and only for as long as that page remains open. Closing the page and then reopening it somehow deactivates IDM, as it will no longer link to the video I want to download. Have tried everything i can think of to solve this, including deactivating all other add-ons and by uninstalling and reinstalling the IDM program itself. I also unchecked the "block popup windows" management tool within Firefox itself. Anyone have any ideas what is happening? Initially, I also received the error message added below, but as far as i can tell, none of my other programs are set to block IDM. The error message no longer appears.

YouTube Input Lag/Delay on Windows: SOLVED

Hi there, not a question but I wanted to put this out there for those who may be running into the same issue as me. I hate searching for things and not finding a straight answer, and I'm hoping that I can bring light to others who may be undergoing the same issue.

I was infuriated by YouTube (and only YouTube) and how slow it was to respond to pretty much any command I sent via my keyboard. Clicking was fine, but if I wanted to skip 5 seconds in the video by mashing the right or left arrow a bunch, it would buffer those key presses and then register all at once. Basically, YouTube was lagging out of its mind and decided that any kind of action I wanted to take on the page would be done incredibly slowly (by modern computing standards, so ~700ms). I play rhythm games, so any input delay more than about 2ms will annoy me to no end.

This ended up being something called GC or garbage collection, and it was "minor GC" and "non-incremental GC" and something to do with a Nursery being full. Whatever that is, switching over to the Call Tree function in the F12 performance menu (F12>Performance>Start Recording Performance>*input commands on video*>Call Tree) told me that the function GC was taking up around HALF of my time recorded. This gave me a place to start at least, and I'm glad that Firefox has this feature and that it's user friendly. I know NOTHING about webpage design or coding, and it wasn't that hard to figure out what was going on.

Expanding the menus was helpful, and I found out that it was actually my Kaspersky Antivirus causing the issue. I dug around for another hour or so and found this helpful article on how to fix it.

A TL;DR from that article is, if you have Kaspersky, go to Settings>Additional>Network and untick "Inject scripts into web traffic to interact with web pages"

This script injection was doing something to slow it down, most likely trying to scan and monitor the inputs I was making on YouTube to be sure I wasn't getting myself into any trouble. Hope that this helps anyone else having this issue, and any moderation can mark this as solved.
