Firefox Community Forum

After an update for Firefox Developer Edition on Arch Linux (I don't know which), my URL bar doesn't show the selected text when typing or pressing Ctrl+A.

In the uploaded image, you can see i typed "e", but it doesn't highlight the entire en.wikipedia.org url. the second result still shows the e's in the URL bolded though.

I've tried disabling hardware acceleration, changing my GTK theme, and also changed my Firefox Theme, yet none work.

When viewing a PDF in Firefox the URL bar indicates the file was downloaded to a temporary folder. If I then select "Save" from the PDF toolbar; or if I right click and select "Save page as" it opens a save dialog to the location I previously saved the same category of PDF to. For example I have separate folders for invoices, if the PDF is my electricity invoice it somehow knows and opens the electricity folder. If it is a water invoice, it automatically opens the water folder.

Whilst this is indeed quite handy, I do not understand how Firefox is doing this; nor do I understand whether this may be a privacy risk in some circumstances and should therefore be configurable.

Hi.

I'm using Firefox 153.0 on Fedora 44 with GNOME 50. Everything is up to date at this date. I know that Firefox is supposed to support fractional scaling on Wayland since version 146.0. However, it does not work on my device.

As you can see, the first screenshot is when Firefox is in fullscreen mode. Fractional scaling seems to work and the text and picture are very sharp. However, when I resize the window, it looks like Firefox does not support fractional scaling (see my second attached screenshot). The text is blurry and not as sharp as when the window is in fullscreen mode.

Hi all,

Sometimes Firefox just closes a couple dozens tabs - I keep around 200 or 300 open - without my request or confirmation. It's not frequent, but quite annoying. Clicking History > Recently closed tabs > Reopen all tabs does not restore all. I don't know where I can find references for the lost tabs or Firefox logs where I could check what happened. My only suspicion is that I inadvertently rest my hand or finger somewhere in my notebook's trackpad, and somehow Firefox understand that as a request to close several tabs at once, but I have no clue if that makes any sense. I didn't test in Safe Mode because this happens too unfrequently for me to tell if Safe Mode avoids the problem.

Could you pls help me finding the reason for that? Does Firefox keep any kind of log I can check? Are there any keboard shortcuts or mouse/trackpad action that can be set up to do this?

Firefox version: 153.0.1 Distro: Linux Mint Version: 21.3 (Virginia) (Based on Ubuntu 22.04 - Jammy) Kernel: 5.15.0-186-generic

Thanks!

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.

So i have bookmarks i don't need anymore and when i click on the ones i want to delete i cant remove it... and so I googled how to remove it and this showed up and you delete everything maybe? Cause i need to bookmark stuff i need to see and use just help me please I'm begging you please.

Hello! I am having trouble restoring my old Firefox profile after migrating my system from Windows 10 to Linux (Fedora). I have a backup file in .html format that is 197 MB in size (originally created on Windows). When I try to select and restore it using Firefox's built-in recovery tool, it throws an error: "Something is wrong with this file. Please try again with a different file." What I have tried (and what didn't work): Moved the file from an external drive to the local Linux Downloads folder (the error persists). Tried dragging and dropping the file directly into Firefox (the recovery page loads, but the restore buttons are missing or inactive due to security/script restrictions). Tried renaming the file extension from .html to .zip to extract its contents manually, but the archiver threw a "Not a zip archive" error. The built-in recovery script fails to process a 197 MB HTML file, likely due to size limits or memory handling on local files. Could you please advise on how to properly handle and restore such a large backup file or extract my data (passwords, history, bookmarks) from it on Linux? Thank you in advance!

Hi! I've received an email informing about my upcoming VPN subscription reneval. But when I went to my subscriptions page I can only see "You have no active subscriptions" message. Does it mean that my subscription is cancelled and the email message is wrong?

Recently everytime I open a page in Firefox I get the message "Open the be link?" "You'll need to choose an application. Before this I got another dialogue box asking me to open the System Handler, but I managed to get rid of that to be left with this new dialogue box. Very frustrating as it interrupts the use of Firefox. Chris

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

I am trying to access my QNAP NAS configuration page within my home LAN from a newly installed Linux PC with Firefox 147.0.1. Firefox won't let me access the page, popping up an error page:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to nessy.fritz.box. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have verified that the claimed risk is nonexistant, but Firefox does not allow me to bypass the warning. There is no "Proceed anyway" or "Advanced..." button as claimed in various help articles.

How can I convince Firefox that I know what I am doing?

NB: The same page is accessible, also with Firefox 147.0.1, from a Windows PC.

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.
