Firefox Support Forum

Hi, I use FireFox (edit - 82.0.4 from LM repos) for my browser when using Linux Mint (I use it on WIn10 as well but this query is specific to LM). I use ClamAV for virus scanning. ClamAV has found Js.Coinminer.Generic-7132237-0 in /home/username/.mozilla/firefox/puhh983l.default-release/extensions/adblockultimate@adblockultimate.net.xpi I've searched and found some mention that it might be a false positive but nothing confirming that info so far from my searching. What have I done so far: Done a fresh reinstalled of ClamAV following the ClamAV install procedure. Checked ClamAV is up to date by checking log files and latest available on the ClamAV website. Done a fresh install of FireFox Reinstalled add-ons one by one. ClamAV only finds the Coinminer once Adblock ultimate is installed/added. I'd like to keep Adblock ultimate as it does what I want it to do easily and efficiently but am happy to remove it to avoid the coinminer (if it is a problem and not a false positive) Can you help or have any advice. Thanks

Cannot sync my bookmarks, logins, extensions in Firefox 84.0.2. Same thing with Ubuntu 20.04 and now Linux Mint latest stable version.

Any tips appreciated. Thanks

Hello there,

I am using Firefox 84.0.3. When I type in the search bar suggestions show up that's ok but I feel a little awkward when I have to press Up/Down arrow to focus items in search suggestion list. Instead want to use the Tab key. If i want to change the search engine i can use Alt + Up/Down arrow.

Thanks.

I have a VMware VM used as a desktop by a team and they've reported that Firefox only shows a blank screen. It doesn't respond to anything, if I click the burger and click options then it doesn't even open a new tab. And I can't even access about:config.

However I've discovered that if I access the desktop via the VMware console then FF works perfectly fine, if I RDP onto the desktop and run FF I get the behavior as I've described.

Even weirder...is if I launch the browser in an RDP session and then seize the session via the VMware console then the behavior stays there until I relaunch it.

And vice versa if I launch the browser in the vmware console and then log in via RDP the browser works perfectly fine until I relaunch it!

What could be causing this?!

I've tried: Disabling hardware acceleration Cleanly uninstalling Reinstalling both the latest version and latest ESR Removing my profile All resulted in in the same blank FF.

No other VM running FF is experiencing this issue, and I'm the only one with rights to modify things.

Any help with this would be greatly appreciated!

Is it possible to save anything Firefox already downloaded? Currently all the “save” buttons seem to mean “download”; even the “view source” button makes additional request which may fail or even redirect (so e.g. clicking that on http://a.b/c may led one to view-source:http://d.e/f if the former page became a redirect in the meantime)

I have set the Downloads preference to "Always ask you where to save files".

When I download a file (I usually download PDF files), Firefox presents the file picker dialog with some directory pre-selected.

I would expect Firefox to pre-select the directory where I saved my most recent file.

However, Firefox often switches between several of my recent directory, seemingly absolutely arbitrarily. It would present the most recent directory e.g. 5 times in a row then suddenly switch to some other directory on its own.

This is EXTREMELY annoying and bad, as it is easy to overlook the changed directory and save the file in an unintended directory. It happened several times to me.

This behavior so destructive and annoying that I would consider it a bug that should get fixed (other browsers do not do this!). However if it is for some strange reason considered to be a feature, how can it turned off and how can Firefox be made to ALWAYS present the most recent download directory?

I'm looking for an extension that I presume exists, but I'm not able to find it: I want to rate websites in the way photo apps allow you to rate your photos, i.e. assign a number of stars to them.

Like https://mozilla.org ★★★★☆

One use case: I'm comparing products where I don't necessarily find something so good that I can come to conclusion now, so I need a way to save it.

Do you know such an extension or have good ideas how to search it?

Hello,

When my Openconnect VPN is on, Firefox takes very long time to open links from outside its own window: ie links opened with xdg-open in Linux (Ctrl+Click). If Openconnect is Off, links open almost instantly as expected.

Here's /etc/resolv.conf when Openconnect is Off. And here /etc/resolv.conf when Openconnect is On: search contains 11 internal domains. Environment: - KDE Plasma 5.20.5 - Firefox 84.0.2 - xdg-utils 1.1.3 - networkmanager-1.26.4 - networkmanager-openconnect-1.2.6 - openconnect-8.09

System proxy settings: No Proxy

What I have tried: - Start Firefox in Safe-mode (no effect) - Explicitly setting Proxy to None / System Default in FF settings (no effect) - Opening links resolvable only inside VPN and just google.com (no effect) Only turning Off Openconnect helps so far. I suspect it's got to do with name resolution (maybe routing as well?), but have no conclusive evidence. Btw, Chrome is not affected by this behavior.

Thank you

# 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

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):

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.

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.

Hi, I'm trying to disable the "restore previous session including tabs" after crash feature.

I've disabled the "Restore previous session" check from the general configuration panel.

I've changed the following values from the about:config panel: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.resume_from_crash = false

However after a restart or shutdown, Firefox still shows up the tabs from the previous session.

I'm using Ubuntu 18.04 OS.

Could someone please help me with this?

Perhaps this feature is useful for some people, but for me it's extremely annoying; plus I really like Firefox and don't wanna change browsers.

Thanks!

This is more of a note for developers rather than a question, but I don't where to send it.

Without any action from me, this web page appeared in a new tab in Firefox: https://technologyto.com/media-capture.html?v=0.3.7&p=0.3.6&type=update (I was away from the PC when it loaded.)

The extension called "Media Capture" is not intalled in my Firefox. It might have been, a few years ago, as I vaguely remember trying something like it. (It didn't work with encrypted streams, so was no use to me.)

Now "Media Capture" does not exist at addons.mozilla.org, and I didn't find "TechnologyTo" at github.

So it's very odd that something has the power to load that page.

I recently made some custom icons for my top sites: uploaded them online, added the custom image url and they looked great. But they don't seem to be working anymore, I only had them for a couple of days and can't think of anything I might've done for that to change.

I can add a different image url and it shows up, in fact, I set the icons both in Linux and Windows and they still show up in Windows. I attached a before and after, what's going on? Thanks in advance

In Ubuntu 20.04, Firefox can dynamically switch between light and dark theme based on system theme anytime. But In other OS ( Arch gnome ) , you have to restart Firefox to refresh the system gtk theme. Is there an api/bash command to do so manually ?

I am using Mozilla Firefox for Ubuntu 20.04.1 LTS x86_64, Version 84.0.2 (64-bit). I really enjoy using Firefox Relay, but I would like to disable the icon in email fields. When I click on the switch that does so, it refuses to toggle off. I've Googled and browsed the forums here, but can't find anybody that's experiencing the same issue. I thought that maybe an extension that I have is preventing me from toggling off, but disabling every other extension changed nothing.

The solution might be easy but I didn't see it

How can I backup my Top Sites customized (pin sites + personalized pictures) ?

I spent too much time on this customizing, and I don't know how many time I had to redo it after it got all removed/ messed up by I guess Firefox Sync ?

I would like my computer to be the primary instance, and that NONE of the other instance could make any change on the primary. Currently I have no idea how it really works, I think that every time I add a device on my sync "family" it mess up my computer Firefox instead of syncing my settings on the new device.

Hi. I always use my browser in maximised windows and in other browsers like Brave or Chrome, I can easily move my mouse pointer all the way to the right on the screen and click the mouse to snap to a particular place on the scroll bar, since the scroll bar extends all the way to the right edge of the window.

However, in Firefox it seems that there is padding on the right side of the scroll bar meaning that I 'overshoot' the scroll bar itself and accidentally click on the padding, which sends the scroll bar flying all over the place.

How can I remove the padding on the right of the scroll bar and get a functionality similar to other browsers? I assume it has something to do with CSS styling, but I'm not very good with that kind of stuff...

When importing browser history from Google Chrome/Chromium only the last few days of browser history get imported to Firefox. I have reproduced this same behavior on Linux and Windows 10 systems with fresh installations of Firefox 84 and Firefox 85. What can I do to import the full browser history which comprises many months of browsing? thank you

i have been trying to add a certificate to firefox using certtutil(from terminal) in my ubuntu machine. The command i'm using is sudo certutil -d sql:$HOME/.pki/nssdb -A -t C,P, -n mycert -i myCert.crt. The same works for google chrome without any error.

Please help me come to a solution. thanks in advance
