I got a new computer and am moving my profile to new computer(W10 to W10). The old profile is 464MB, mostly in Storage/Default 234MB I think this is a lot and want to slim it down. I want to keep bookmarks and have it auto recall previous sites I have visited. Can I keep the bookmarks and auto recall, but delete some of the files? These files are big also, places.sqlite, webappstore.sqlite, favicons.sqlite Thank you very much.

I have to say that this has been the most frustrating issue that I have been unable to find any kind of help with.

I am running W7 on this laptop (I do not know more than that), even W10 on my desktop, both with the most updated version of mozilla.

I have removed the adobe flash player, and now I cannot get any videos to play, like on CNN and other various sites. I just get the spinning wheel of nothing. It seems that only you tube is working, barely.

Am I missing something, is this open html5 crap supposed to just take over and everything will be okay.

Maybe someone, somewhere can post a layman's explanation on what is going on. If there are issues, how to fix them. I don't need anymore information telling me how to remove because it is dead. What I need is what is replacing it, how does it work, and where and what can I do to fix issues.

Searching for help here on this subject is just tedious. I get over 3000 replies, or what ever they are called here, but just nothing on an explanation of what is changed and or how it works, more like doesn't work.

What do I need to do in order to be able to watch/play videos online.

Any help would be very, very much appreciated.

Thanks in advance.

Hello, for the past week i've been tackling this problem and it's driving me nuts. I've basically replaced FF with Chrome at this point, because I can't use it for work.

Firefox refuses to print, no matter which printer I select, and even if I try to print to .pdf using Microsoft Print to PDF (or other, 3rd party ones, I tried). Other programs and browsers print just fine, it's only FF that refuses, and it refuses to do so with any printer, physical or virtual.

The error I get is a window titled "Print Preview Error" and the error message is "An error occured while printing" (see attached image). For what it's worth, when I go to the menu and select Print, I get the print preview just fine, it's only after I move on to the printer selection and click on Print that I get this error.

I've followed all the steps from: https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox as well as: http://kb.mozillazine.org/Problems_printing_web_pages#Reset_printer

And I've also tried using Safe Mode while doing that, as suggested here: https://support.mozilla.org/en-US/questions/854093

I hope you can help! I've been a Mozillian for more than 20 years, contributor, and volunteer, but this is making my work impossible and I'm forced to abandon FF due to this problem.

This question has been around for years... Isn't anyone else annoyed by having to clean up UNPINNED Top Sites one at a time? I posted over four months ago about trying to find out where Top Sites stores those unpinned sites... no one seems to know, except to say they are placed there by Firefox internally. I presume that means it is hidden in the code somewhere. Someone on the development team must know where? Maybe if there was a poll of users about this annoyance?? I wish I was younger to be able to get back into coding... my old brain just isn't up to it... ________________________________________________________________ You can lead a horse to water, but you can't make 'em think...

Does anyone have experience with this phenomenon:

When you click on a torrent link on a page opened in Firefox 83 (and above), the first window pops up, but the second one (in which uTorrent would come) is no longer. Nothing happens.

If I revert to Firefox 82 or 78.6esr, the error will not occur.

If I choose not to download uTorrent but to download the torrent file, it works fine with all versions of Firefox.

# Ubuntu garbage data increases exponentially
## 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)

## 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.

I am a reseller and use different sources. One of our vendor's websites is showing me retail pricing after I login. Our special prices used to (and are supposed) be visible. If you don't log in, no prices are visible. My sales rep asked IT, who said to clear cache and cookies. And again today, he said it is on my end, not theirs.

Of course, that doesn't solve the problem. Do not even know where to begin.

I have configured FF to block all cookies under "Browser Privacy" the custom setting allows "Choose which trackers and scripts to block. and I selected "all cookies". Knowing that all cookies will be blocked I logged into office 365 and allowed manually cookies through "view page info" I then selected "set cookies" to allow expecting full access to office 365 mail, but this did not occur. What happened is I logged into office 365 and could see the icons and my login name but could not read the mail.

Office 365 gave the message "we couldn't sign you in please try again" yet I could see my log in name and the office 365 icons for mail, calendar etc.. just not the actual data. If I allow cookies in Browser privacy (which i take it allows cookies always) it woks.

I bring this up because it seems like something is missing in cookies that is not represented in FF.What is the difference between browser privacy cookies and allowing it through view page permissions? Can anyone offer an explanation?

Hi,

My Firefox sync data for a specific addon is messed up. I believe the temporary containers addon made Multi Account Containers addon to sync an insane amount of containers, maxing up the sync storage. Now whenever I click to sync MAC, it downloads thousands of 'tmp' containers. It refuses to sync ever again, hence no matter how many times I fix it locally, if it ever syncs again, it downloads the thousands 'tmp' containers again. How can I delete the sync data for good?

All was good until sometime today. FF 84.0.2 W10 up to date. Previously, when browsing FB marketplace, i could send a message about an item for sale. That send message button is now greyed out. The messenger button on the top right of my screen used to open a dropdown/popup that gave me a summary of my messages. That no longer works. I have been thru all kinds of settings randomly on FF and FB to try and correct the issue but i cannot figure out what is going on. I have tried turning Ublock on and off but that has not helped either. The only access i now have to messenger is to open it separately. I have not changed any FB settings. I did not change any FF settings myself other than trying to find out what could be doing this and exploring ublock for possibilities as that seemed the most likely culprit. Can anyone shed some light on what the issue is.

The last time I updated Firefox I had such a bad time I swore never to update it again, however yesterday an addon I use couldn't work without updating. So I bit the bullet and did. I've been regretting it ever since. At best it works slightly slower than my old version which was 61.0.1. At worst I miss the days of internet explorer.

The most common issues are 1. White Wheel: When I swap tabs or open a new one I often get a spinning white wheel. This can last anywhere from seconds to at least ten minutes. I've asked around and tried everything suggested, nothing has gotten rid of it.

2. Scripts breaking: This started later on after installing it. Almost any time I refresh a tab or open a new one a script in some other tab breaks. At least twice I was just watching a video in one tab, not even touching the computer and a script breaks in another tab.

Please, I just want my browser to run properly. WITHOUT having to sacrifice my settings/history/bookmarks/addons

I usually watch YouTube video's at 1.25x speed, and I noticed recently that it seem to make some audio distorted. So far I've only noticed it on lower notes, but it causes to sound a bit distorted and warbled.

I noticed it on this video: https://youtu.be/IubSudelVmw?t=429 at the tagged time, and also on a channel called The 8-bit Guy on his intro theme. https://youtu.be/d3NIe1jTZMc

Again, this is all at 1.25x speed (or faster), and this only seems to happen in firefox. I made sure to check and see if it was my speakers, which it isn't because I can also hear the distortion through headphones.

I'm not sure there's much to be done to correct the issue, but I thought I'd post about this in hopes it might get checked in a future update.
