I created a tar.gz back-up of my /home folder prior to doing a fresh install of UbuntuStudio 18.04. (The previous version was Ubuntu Studio 16.04, and it wouldn't let me upgrade, so I had to do a whole new installation.) I never "exported bookmarks" because I never realized I could do that! However, I was sure there must have been bookmarks already kept somewhere in my /home folder. However, now I can't figure out how to get at them. Although I can extract all kinds of files dealing with Firefox, I can not figure out how to access or generate Firefox bookmarks from all those files that exists. I'll try to attach a photo of my terminal output for what I can extract from the old /home that had "firefoxbookmarks" in it's name. Can anyone please help me.

But in case it doesn't upload here is my terminal output: usr/share/unity-scopes/firefoxbookmarks/ usr/share/unity-scopes/firefoxbookmarks/__init__.py usr/share/unity-scopes/firefoxbookmarks/unity_firefoxbookmarks_daemon.py usr/share/dbus-1/services/unity-scope-firefoxbookmarks.service usr/share/doc/unity-scope-firefoxbookmarks/ usr/share/doc/unity-scope-firefoxbookmarks/copyright usr/share/doc/unity-scope-firefoxbookmarks/changelog.Debian.gz usr/share/unity/scopes/web/firefoxbookmarks.scope usr/lib/python3/dist-packages/unity_scope_firefoxbookmarks-0.1.egg-info var/lib/dpkg/info/unity-scope-firefoxbookmarks.md5sums var/lib/dpkg/info/unity-scope-firefoxbookmarks.list usr/share/unity-scopes/firefoxbookmarks/ usr/share/unity-scopes/firefoxbookmarks/__init__.py usr/share/unity-scopes/firefoxbookmarks/unity_firefoxbookmarks_daemon.py usr/share/dbus-1/services/unity-scope-firefoxbookmarks.service usr/share/doc/unity-scope-firefoxbookmarks/ usr/share/doc/unity-scope-firefoxbookmarks/copyright usr/share/doc/unity-scope-firefoxbookmarks/changelog.Debian.gz usr/share/unity/scopes/web/firefoxbookmarks.scope usr/lib/python3/dist-packages/unity_scope_firefoxbookmarks-0.1.egg-info var/lib/dpkg/info/unity-scope-firefoxbookmarks.md5sums var/lib/dpkg/info/unity-scope-firefoxbookmarks.list

I am using firefox in linux mint basically and today I noticed that when I click on a youtube link it opens my firefox and then the youtube website and the video loads but the video doesn't play and keeps buffering when I click on the play video button. And then if I click on other youtube video those doesn't work too. So I have to close firefox everytime and then when I manually visit the youtube website everything works. But if my browser is closed and then I click on the youtube video it loads the video but doesnt play it and keeps buffering.

Firefox needs a limit on memory usage. I was developing a tiny web page on Linux (PopOS) and accidentally created an endless loop in Javascript that ate memory (by growing an array). My entire OS became inoperable and had to be hard-rebooted. I was surprised this could happen due to Javascript (a sandboxed browser language), running in a web page (a sandboxed app) running in a Firefox browser that is supposed to protect users from the world wild web. One errant line of legal Javascript in HTML should not equate to a denial-of-service attack.

A sensible approach would be similar to the nice warning given when a script takes too much CPU, offering the user the choice to continue or stop the script when a tab exceeds some reasonable size: a fixed MB size, or say 10% of real RAM memory.

Ideally there should also be some hard limit calculated by Firefox according to the machine's available memory and Firefox's reasonable percentage of it. For example, maybe limit Firefox (all tabs combined) to 50% or maybe 75% of real memory, so that the O/S has a reasonable chance to remain operational so that a bad tab can be closed. Otherwise, Firefox could cause the O/S to lock up, resulting in data loss if there are tabs or other apps outside of Firefox that have unsaved changes.

Thanks for your consideration!

I'm pissed of. HOW??? HOW??? How a single browser can take 90% of the memory until freezing your PC, ON A LINUX MINT FOR GOD SAKE! With 16GB Memory!

I saw people defending this saying that "uuuh, mozilla takes advantage of-" BS! It doesn't take advantage of nothing, it only wastes your ram and your time.

HOW DO I LIMIT THE RAM USAGE? I DON'T WANT FANCY PERFORMANCE TABS I WANT A DIRECT ANSWER ON HOW TO STOP FIREFOX WASTING MY RAM

Hello, I am using Firefox for many years with Ubuntu but recently Firefox started to transcript Cyrillic page into Latin ones. I tried to change some of the language settings, but nothing worked. My standard language is German. How can I make Firefox show the pages in Cyrillic alphabet? Thank you for your help.

My current FF version is 88.0 [64 bit]. Websites are flagging FF 88.0 as outdated. There is a 88.01 version shown as available. Latest available FF version is 93.0

Updating using the Help > About function does not show any available updates. Can someone please explain what is going on? Thanks.

I am using Firefox 93.0 on Archlinux, with Kde Plasma 5.22.5 and since yesterday a very strange issue is happening.

Only when I use my Firefox' Work Profile, the mouse cursor hitpoint is misaligned from the tip of the pointer.

For example, for the arrow cursor, the hit point is on the left a few pixels below the arrow tip. For the text caret cursor it is even worse as the hit point lies outside the cursor itself, about 5 pixels below.

This happens not only within the pages, but also on the tabs, bookmarks, tabs, menus and even the settings page, as can be see in the partial screenshot attached. As per the cursor position, the "Advanced" button should be highlighted, but "Colours" is highlighted instead.

This DOES not happen with any other program on the same linux session and not even on firefox when using my private profile.

I have tried disabling extensions, but that did not change anything.

I am not even sure where I can start investigating or troubleshooting this, appreciate any suggestion. Thank you.

Hi! so I installed Kubuntu 20.10 after using it 'directly from the cd' for some time. since, all data would be lost every time i restart, i would keep a copy of a '.mozilla' file i would find in the system. Everytime i start the OS, i would first create a folder and copy paste it, so firefox would start right where i left it off. this worked, until i decided to make Kubuntu permanent. at first things were going good, but after sometime, my OS would stop recognizing my headphones and audio port completely. at first i blamed it on my OS and went about doing somethings here and there to adjust by. but looking back, i had installed some DRM to play some video on the net. so in a desperate fix, i replaced the current .mozilla file with a backup i had. the thing worked like a charm and my audio was fixed and everything was going ok, except for the occasional fixes so that my OS would channel the audio to the right output. that is, until the problem rise again! this time, i hadn't installed anything like i did previously, so i replaced the .mozilla file again and it worked! but i can't keep doing this and i had also faced the same problem in my windows, resulting my change in OS in the first place (I think its the same issue, because whatever i did didn't fix it and windows is more sophisticated that i wouldn't know). I don't know if this much info is too much or too less or that if i should post this here or in any other forums, but i would really appreciate it if i got a solution! Thankyou!

Starting as of today (Oct 13), the FACEBOOK screen suddenly moves when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts about a page up, closer to top. This shifts the entry area where I'm typing down and off the screen. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. It is maddening!

I've restarted in troubleshoot mode and the same thing happens, so it is not an add-on. This is happening on both my Firefox Linux systems AND on a Windows 10 machine, so I don't think it is specifically OS related either. The screen however does stay put, like it is supposed to, using Chrome or Opera.

Is this a Firefox problem or is FACEBOOK messing with Firefox?

If you don't touch the autoplay permissions for a site, Firefox seems to be attempting to use some heuristics to decide whether autoplay, such as calling ".play()" on an Audio object in javascript, should be allowed. What are these heuristics, and where are they authoritatively documented? [https://developer.mozilla.org/en-US/d.../Autoplay_guide#autoplay_availability|MDN] has some information but nothing Firefox-specific.

Hi, I have a Librem Mini running PureOS based on Linux Debian. I downloaded the binary package of Firefox from the Firefox download page, but may not have installed it properly. I can only run the browser by going to Files, Home, double click the Firefox folder and double clicking the file Firefox. Works perfect, but would like to have the shortcut in my Applications window like all of my other apps. Can anyone help? Thanks, Chris

Dear Supporter,

I got a notification from a website that FireFox is not up to date. On closer examination, this is indeed the case. Updates were supposed to be done automatically.

I changed Ubuntu's update server to main server; this had no effect.

In settings preferences under updates I see: FireFox Updates Keep FireFox up to date for the best performance, stability and security. Version 88.0 (64bit) Whats new Mozilla FireFox for Ubuntu canonical – 1.0

There is no option to check or disable for automatic updates. As far as I can remember, update to this version was automatically.

In settings help under About Firefox nothing appears about updates.

OS is Ubuntu 16.04 LTS notification: system-up-to-date I assume that should be allright?…

Thunderbird is 68.10.0 That seems ok...

Thank you very much

Hello there. I am using Firefox 78.130esr for openSUSE Leap 15.3. It is a clean OS installation. Firefox won't connect to Google sites. It does connect when I just open Firefox but after a couple times I connect to google.com or try to read my gmail, it does not connect anymore and there are no error messages, just an empty screen. I tried the solutions proposed in https://support.mozilla.org/bm/questions/1243633, namely cleaning cache and cookies, disabling extensions, no proxy, and even refreshing Firefox, and the result is the same. It does connect to other sites. Google Chrome and Chromium can connect to all sites.

Thanks in advance,

jvleon

Hello. I have a Firefox Account and I wanted to log in into it, I went to my authenticator app but I couldn't find the Firefox entry and I couldn't find the backup codes either (I lost them while reinstalling the OS). I can confirm I own the E-Mail address (I have my own domain).

Hello,

I have the current Firefox version (93.0) running on XUbuntu 20.04.03 LTS. Accidentally pasted the URL of a known phishing site (obtained from Phishtank) into the address bar instead of a VirusTotal search box, and it browsed to the site. Verified in https://transparencyreport.google.com/safe-browsing/search?url=https:%2F%2Fdocs.google.com%2Fforms%2Fd%2Fe%2F1FAIpQLSeAhelw8U_QuFyvJDmAn4aYM-H6QXYahD7ZjaFXC6CdyuxaNQ%2Fviewform%3Fusp%3Dsend_form&hl=en that the site is blacklisted.

I thought that Google Safebrowsing is enabled by default? (Checked about:config and saw that the "safebrowsing" settings that are bold are the ones with timestamps e.g. lastupdatetime and nextupdatetime.)

Hello, I'm using Ubuntu 20.04, and the newest Firefox (i.e. 93.0). For a long time already I have very irritating issue: I have 2 profiles: Company (default) and Personal (secondary). Company profile is marked as default. Personal profile I'm using for my personal email account, youtube, facebook etc. The issue is that whenever I have opened 2 FF instances, with those 2 separate profiles, I never know in which instance of FF the link will open. It's soooooo frustrating. Mainly I'm opening links from company Slack or email, and I never know in which Firefox link will open. Is there any option to set it? I would except that all links will open in the default profile ("Company"). Br, Marek

I opted out of Mozilla Rally and I still get a popup every time I open my browser that says Rally Required and asking me to install rally because I'm missing the rally add-on even though I opted out. The Website: https://rally.mozilla.org/rally-required/index.html

I accidentally ignored a website which pops up in my Firefox home screen. Now it doesn't reappear no matter how often I visit the site. How can I undo this action?
