Firefox Community Forum

Everytime I try to access myAir.resmed.com I get a blank screen. When I do it with google chrome it works. Something set wrong in settings but can't find it.

First came the Linux upgrade and with it the enforced new Firefox version. The new Firefox appeared "raw" with none of my previous settings. I am having trouble filling in the Firefox toolbar and recovering things like "most visited" sites listing and many others. There must be a common sense limit to the "happy developers'" ideas.

Hi - new to the forums.

I have a fairly retrograde, request :slight_smile:

I want to have Firefox operate with ONLY ONE tab on screen at any time!

By That I mean, whenever I try a new search ,or open a new link, I want it to REPLACE the one and only existing tab always. Firefox will only ever have one tab on the screen- no multiple tabs allowed.

Is this possible?

Many Thanks

I want to: - Delete cookies, logins and cache of all not specifically allowed websites when closing the browser - Automatically delete the browser history of anything thats older than 'n' days or entries - Preferably do this without having to use an addon

I have set places.history.expiration.max_pages, however even on a really low value it does not seem to delete any older items from the history.

For deleting cookies and cache I have a problem understanding how the 2 sections in the settings interact (Cookies and Site Data and History) and how I would manage to delete everything except the whitelisted cookies.

I am running firefox installed through flatpak in Debian 11. From the last update, 112.0 and 112.1, some websites for some reason do not show the text scripts as they should. I attach an example from a website, first with firefox 112.1 (where some text script does not appear) and next from firefox 102.10.0esr (where all text appears).

After running `snap refresh firefox`, many sites I use no longer render any text.

Via some fiddling via the developer console, it appears to be that any text with `font-family: Helvetica`. Removing that CSS restores the text, adding it removes the text.

There's a fix for CVE-2023-29537 in this release that affects font initialization - possibly related?

Most of my bookmark folders are listed chronologically based on when they were added. One folder changed to alphabetical.... How do I change it back to the way it was for the order of the folder contents?

When I check for FireFox updates, the message states "Firefox is up to date" or similar. However, the currently installed browser version is 68.11.0esr. I've seen higher version numbers so, I don't think this is correct. I've read many help items, FAQ's, etc, including those by Firefox, and yet can not determine the process to remove the current browser version and install a later version.

Hi Firefox Team,

is there a way to change the available paper-size formats in the "Save to PDF" dialogue (A3,A4,US,...)? I would like to select e.g. A2/A1/A0, or ideally even custom size x/y measurement.

Enclosed an image of the dialogue. I am on Linux, Firefox 111.

I could be wrong, but didn't the dropdown menu contain at least A0-A2 around 1-2 years back? Is it correct to asume, that the "Save to PDF" paper-size selection is not influenced by OS-related printing configurations?

Thanks and best regards

Hello everyone, I wrote an add-on for my own personal use. I don't intend to publish it. So naturally, it isn't verified, but I trust it. I am able to install the add-on as a temporary add-on under about:debugging, and it works as intended. The manifest file contains "browser_specific_settings": {

       "gecko": {
           "id": "example@example.com"
       }

} I would now like to install the add-on permanently. So I packaged it as a zip file. The zip file contains the files directly without a parent folder. Under about:config I set xpinstall.signatures.required, xpinstall.whitelist.required and extensions.langpacks.signatures.required to false. Then I went to about:addons clicked on install add-on from file and selected the zip file. I got the error message: "This addon could not be installed because it has not been verified". I am using Firefox for archlinux, version 112.0.

What am I missing? How can I install this addon?

I apprechiate your answers.

Updated. See bottom for up-to-date question.

Hello! :) I'm on a pretty fresh install of Debian bullseye. Immediately after launching Firefox ESR, it crashes. Not always, but every ~2nd launch. The Mozilla Crash Reporter "We're Sorry" appears and the crash looks like this in terminal: mars@desktop:~/Desktop$ firefox ExceptionHandler::GenerateDump cloned child 83677 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... mars@desktop:~/Desktop$

I tried making a fresh profile without addons/settings, and it still crashes but less at every ~6-7th launch. However, it does not crash in safe mode, though visiting websites while in safe mode is laggy. Here is the terminal of safe-mode: Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs Sandbox: Unexpected EOF, op 0 flags 00 path /proc/cpuinfo

Any idea? Thanks in advance!

Extra observations:

• Didn't have these issues with Firefox on Fedora (Wayland) and Gentoo.
• Toggling Caps Lock takes about half a second to activate/deactivate in Firefox, resulting in a lot of accidentally capitalized letters.
• Generally, Firefox seems pretty slow and scrolling through items/websites with images is a bit choppy. Websites load slower compared to my forementioned distros.
• Not sure if it matters, but I installed Debian with automatic/guided (encrypted LVM) and noticed after that my swap size is only 980 MB when my RAM is 16 GB. Just mentioning it in case it's relevant.

System info:

• DE: XFCE with x11.
• Kernel: 5.10.0-21-amd64.
• GPU: NVIDIA contrib non-free driver. Force Composition Pipeline ON. Allow Flipping OFF. TripleBuffer ON.
• CPU: Intel i5 6600K

UPDATE: I found the cause of the crash. If I enable Use hardware acceleration when available, Firefox crashes on launch. If I disable it, it doesn't crash which is nice. BUT, it leads to unbearable lag and puts my CPU usage to 70-100% when dealing with videos or images. This exact thing happens on two fresh installs on different SSDs.

Any advice? Do I need some additional drivers for my Debian install? Thanks!

Info:

• Debian Bullseye.
• Firefox ESR 102.10.0.
• GTX 970 w/ proprietary nvidia-driver.
• GNOME on X11.

Hi, I made a theme but have since not used it and swapped to another. Everytime I open the browser, it swaps back to the one I made for some reason. Under themes, it will still say the one that is showing is the chosen theme, but it most certainly is the one I made. I turn on another theme and toggle back to the chosen theme and it then changes correctly. Any idea why that could be?

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

For several years now Firefox keeps the methodology to update in the background and then force the user to restart.

This always causes some loss.

There are multiple situations where this is not acceptable. Just to give one example: I just logged in an account and clicked to receive an authentication SMS. But then Firefox forced restart and I cannot login nor ask for a new SMS because the previous request was recent.

In my opinion this makes absolutely no sense. Is there an option the turn off this forced restart?
