Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

How to verify offline Firefox installer using its .asc file

I have downoloaed Firefox offline installer (a .xz file) from here:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/139.0b9/linux-x86_64/en-GB/

I have also downloaded a .asc file, presumably a pgp signature.

Now both files are saved locally in my computer.

Assuming Linux latest release, how do I verify the contents of the offline installer file (.xz) from the Linux Terminal? I have install gpg tools. And commands like ```gpg``` are available.

What I did so far:

 gpg --show-keys --with-fingerprint firefox-139.0b9.tar.xz.asc

with this output:

 gpg: no valid OpenPGP data found.

Do you really want us to verify the contents of the installers you provide? A sha256 sum would be great, though not as secure, for when the GPG predictably fails for the ordinary user due to its huge and useless complexity and bureaucracy.

However, I wanted to add hone button and a few other mods to the toolbar but when I started customize the toolbar from menu pic the customization page would not work, it appeared and seemed OK but when I dragged and dropped anything it would not work. I could pickup items but they would not place in toolbar and just snapped back to the pallet. I tried several different ways to enter the customization area but it was always non-functional.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Probably nothing, since it’s likely there’s a problem with the site itself.

When I encounter an embedded video on a website that plays, an icon to toggle picture in picture pops up in the URL bar (see attached image). I don't use picture in picture, and for some websites which have an "endless scrolling" experience with videos, such as reddit or facebook, it is slightly annoying that while I am focusing the middle of the screen, something changes in the top right, making me think a tab has an update and changed title. I have the picture in picture controls turned off in settings (one with the id=pictureInPictureToggleEnabled in general, my Firefox is not English), I thought it would also make said button go away but it does not.

Is there a setting to always show the translation icon in the Firefox desktop address bar?

  1. Scenario

I'm visiting a website that is not in my native language. For example, I natively speak English, and the website contains Spanish text.

The Spanish website incorrectly sets lang="en" in the HTML. Here's an example: https://animalessinhogar.com.uy/

My browser's default language is set to US English. When Firefox sees the Spanish webpage declaring the lang="en" tag, it assumes the webpage is in English, and hides the translation icon from the address bar.

  1. Issue

The end result is I see this website in Spanish, there's no translation icon in the address bar, and also no way to force a full page translation. The best I can do is select parts of the text, right click, and ask for "Translation Selection to English". This gets very tedious, especially when I have automatic translations for Spanish websites already turned on (browser.translations.alwaysTranslateLanguages = es).

  1. Proposed solution

To work around these websites which mis-declare their language, is there a way to always show the translation icon in the address bar?

I had also thought of removing my browser's default language, so that the translation icon would always appear on every webpage. However, that would mean that websites that present different versions based on browser language wouldn't display my native language at first, or might not work at all? So this seems like a less good solution.

  1. Firefox details

140.4.0esr (64-bit) running on Debian Linux 13 (Trixie)

Here's some related Firefox config options for translations, and their settings on my browser. I think I've only changed the configuration option to always translate Spanish webpages.

browser.translation.neverForLanguages browser.translations.alwaysTranslateLanguages es browser.translations.automaticallyPopup true browser.translations.chaos.errors false browser.translations.chaos.timeoutMS 0 browser.translations.enable true browser.translations.logLevel Error browser.translations.mostRecentTargetLanguages en browser.translations.neverTranslateLanguages browser.translations.newSettingsUI.enable false browser.translations.panelShown true browser.translations.select.enable true browser.translations.simulateUnsupportedEngine false browser.translations.useHTML false browser.translations.useLexicalShortlist false gfx.canvas.remote.use-canvas-translator-event true services.settings.main.translations-models.last_check 1773722950 services.settings.main.translations-wasm.last_check 1773722950 toolkit.telemetry.translations.logLevel Error

The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

Is there any variable that I can use to pass the full URL including parameters of the URL?

Hi, my Machine updated from 140.0.4 to 141.0 since then I cannot start up Firefox anymore. On startup after a short pause the Crash Reporter shows up - interestingly the Crash Reporter may enter a endless loop and opens up multiple times. While that the CPU load is at 100%. I tried

as well, for those I get the same behavior. I tried downgrading to 140.0.4 - after that a profile dialog shows up which tells me that a new profile needs to be created due to a downgrade. After that Firefox comes up fine with the new vanilla profile. IF Firefox updates to 141.0 (in background) the next startup with the vanilla profile doesn't work gain. Which brings me back to the initial problem.

Workaround for now:

  • download 140.0.4
  • create a fresh profile
  • immediately disable auto update
  • live with the empty profile

They do change appearance in response to picking the different styles in Settings > Appearance, but the changes appear to be limited to colors only. The minimize, maximize and close buttons look differently than on all other windows, and they are more spread out than in, and the shade button is nowhere to be found.

I'm attaching two small images, the first one is the standard set of widgets all other windows have, and the second one is Firefox's odd duck. I could not find anything in settings. "Extensions And Themes" shows that "System theme" is enabled. Well, it's coming up a bit short...
