Firefox Support Forum

My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

I was set up, in myuserchrome.css, to hide my pinned tabs on the tab bar, allowing them to still be available in the "List all tabs" menu, see first image

.tabbrowser-tab[pinned="true"] { display: none !important;}

All of a sudden, it reverted back

That first image, with the hidden tabs, is actually from Librewolf, with has the identical setting.

Hello all,

I'm building a website which uses a `ServiceWorker`. This worker uses `import` to load another JS module. As far as I understand, this should be possible starting Firefox 114 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#browser_compatibility). However, it's crashing with an `TypeError: ServiceWorker script at https://localhost:9292/sw.js for scope https://localhost:9292/ threw an exception during script evaluation`. The worker script is loaded as module using `navigator.serviceWorker.register('./sw.js', { type: "module" })`, and working on Safari and Chrome as expected. When I remove the `import`, the worker loads and works. Tested on Firefox 118, 119, 120.

Here is a full sample: https://gist.github.com/fnordfish/9b38b90fba54093ee601887a3bd3e11e

I can't find any related bug in Bugzilla or anywhere else. Which makes me wonder what I am missing.

PS: Non module `importScripts` work.

Very recently, I was typing a ton of content into a website textarea, when my Firefox Nightly install crashed. I lost all of this work from hours. Is there any way to get access to this data?

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.

Took me a long time to nail this issue down. Recently (past 1-2 years?), Firefox has started suggesting the base website when you have bookmarks that include the base domain - and it's really bothersome from a UX perspective. E.g. if i have "adobe.com/express" or any other adobe bookmarks, the FIRST autocompleted url Firefox gives me is "adobe.com" which I DO NOT have as a bookmark. In my Firefox settings I also have Shortcuts and other search suggestions disabled.

Why is Firefox doing this?

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.

I'm not really sure how to categorize this question, so I labeled it Other.

I use Firefox v118.0b9 with Windows 11 and the clipboard api works as expected. However, I have a friend in Denmark that uses Firefox v117.0.1 with Windows 10. He tells me that the copy to clipboard function that works for me doesn't work for him.

Anyone using the same version as he is can check it out here:

There are 5 buttons with copy icons. Each copies a specific puzzle solution or the puzzle itself. Is there a reason it does not work with that version of Firefox but does work with the version I use?

for new file types the option to save the default behaviour for future downloads is no longer avaliable for me. Also, the option to set in "Settings -> General -> Files and Applications" does not show any of the new file types.

I've tried re-installing firefox, as well as refreshing but still the same results.

The default location of the new bookmark is set in about:config，that is browser.bookmarks.defaultLocation. How can i change it with JavaScript in third-party extensions？

My chat sends garbage. Here I type 'test' to my son. Here is what my chat shows after I press RTN:

2255821536##7637873208AQL/23VRnm9YyO/TaA1HjcHgyffG3PWzb1qU7wbh6N/XZXp1wqd5roGoLrrc92GowtY2Rwkb2255821536##7637873208

I'm having an issue with a particular text field. When entering any text into said text field, my CPU will shoot to 100% usage on some cores, hang for a bit and then print the text after a few seconds. I have an Intel 13900k @ 5.5ghz.

I can't provide a link to the text box as it's a WordPress CMS on my local machine. This issue does not present itself on the competitor browser.

A few troubleshooting steps I've taken:

• Re-install Firefox
• New profile
• Disable all extensions
• PC safemode + Firefox safe mode
• Tested dev/nightly/stable (I'm using BETA daily)
• Disabled accel

Hopefully I'm able to have an expert look at my profiler to help determine what the issue is. I'm not knowledgeable in this area unfortunately. https://share.firefox.dev/3s60ISV

Thank you.

On some sites like youtube, crunchryroll, and other sites usually where it's main purpose is to play videos my sound plays fine. However, on other sites like osu's website, chess.com, duolingo, and others, there's no sound at all. I've tried refreshing, restarting, running in safe mode, and even reinstalling the browser but none of it has worked. My tabs are also not muted. Does anyone know how to fix this?
