Title: [Source Map Loader] Worker crash due to unhandled JSON.parse error on non-JSON/HTML responses in fetchSourceMap.js

Description:

When fetching source maps in a worker context, fetchSourceMap.js occasionally encounters an unexpected non-JSON response (such as an HTML error page or 404 response starting with ). This causes an unhandled JSON.parse exception at line 83 (_fetch), crashing the source map consumer.

Stack Trace: Plaintext

Source map error: Error: JSON.parse: unexpected character at line 1 column 1 of the JSON data Stack in the worker: parseSourceMapInput@resource://devtools/client/shared/vendor/source-map/lib/util.js:163:15 _factory@resource://devtools/client/shared/vendor/source-map/lib/source-map-consumer.js:1069:22 SourceMapConsumer@resource://devtools/client/shared/vendor/source-map/lib/source-map-consumer.js:26:12 _fetch@resource://devtools/client/shared/source-map-loader/utils/fetchSourceMap.js:83:19

Proposed Patch (fetchSourceMap.js - Line 83): JavaScript

// Replace direct unhandled parse at line 83 with safe parsing: const sourceMap = (() => {

 try {
   const trimmed = responseText ? responseText.trim() : "";
   if (trimmed.startsWith("<") || trimmed.startsWith("
})();

I've searched & waited past few years for an Extension to make the TOOLBAR FONTS larger, none found. Reason being many of us are using larger monitors and TV's and we're usually sitting or standing further away from the screen. Problem is the font size cannot be changed, they stay small and hard to read comfortably. __YES I've reset my operating systems font size, that does not work in Firefox TOOLBARS. __Changing the "firefox/addon/theme-font-size-changer" has been eliminated by Firefox. __Changing the "layout.css.devPixelsPerPx" to a larger number increases the whole TOOLBAR. I just want the FONT size larger. __(someone suggested) NO, I'm not going to setup 2 monitors.

Sure would like this issue fixed. In the pix below, it has been done.

After a Windows update, Mozilla my browser times out and won't load: "http://www.dailygammon.com/bg/login" It has been one of my bookmarks for years, I play Backgammon there every day. I have cleared my browser history and cache, it is still not loading. I tried with Edge and it loaded no problem. How do I fix this? Mozilla is my default browser.

My spell check generally doesn't work, but occasionally comes back to life, I have tried the about config, and change value to 2, I have tried uploading dictionary, and making sure check as I type is ticked, but the setting on config seems to keep reverting to 1, and I'm sure if I have successfully uploaded a dictionary, I clicked on language pack, Ironically while I'm typing this, my spell check is actively involved.

Fonts in the digital issues of the LA Times are changed. They appear as serif initially, but quickly change to a sans serif which appears to big for the space. The headlines are squeezed together and touching. Body copy is affected also. How to keep the fonts as they first come in?

At some point, I was issued Auto-generated passwords, but they were not saved even though I believe I have things set up to do so. Other passwords are also not saved. I cannot update my 2015 Mac's OS above Monterrey. Please advise.

I note that this problem has been going on for more than 5 years and is STILL a glitch with your otherwise excellent product! Strangely it has only started happening to me though since I got my new PC. It really shouldn't be beyond you to provide an update with a permanent solution rather than having to close a window before it is saved as suggested on a 5 year old forum.

Please fix this now - 5 years is a long time in the IT world!!!

Recently when i go to a new url in Firefox, it often takes me to the very bottom of the page right after it loads. For example, it just happened on fidelity.com. I haven't changed any app settings, but there have been app updates. Can anyone help?

I've been using Firefox for a couple months now, and I just ran into this problem today with English text nearby Japanese text: https://files.catbox.moe/diw4y3.png

• It's not affecting Japanese text
• It's not exclusive to Japanese websites (it's present in one email in gmail, but not all of them)
• I haven't seen it on any Japanese websites
• It's also present in some add-ons that generate text (Checker Plus for Gmail, Yomichan)
• Turning off all add-ons doesn't fix it, but opening the page in a private window does fix it

Firefox 155.0.1 (64-bit), Windows 11 Pro

Installed Firefox on new laptop that has MS Edge, but Firefox is default browser. Downloaded and installed Norton Password Manager to both browsers - no problems with Edge install. Extension downloaded to Firefox, but when trying to log-in to Norton account, Firefox returns error message: Norton Password Manager Sorry, something went wrong. Please try again. Suggestions?

I get 'you browser cannot play this video" when I try to watch NFL Sunday Ticket on Youtube; what causes this? I use Linux Mint on my laptop.

I also have Opera browser installed; I get the same error using Opera.

Please help. Thanks.

Recent update nuked all my custom containers, and closed every page that was currently open within those containers (pretty devastating bug).

Now, I go to add sites to the new custom containers I made to replace the earlier ones. When I go Manage Containers > pick a custom container > "manage site list ..." and there is no list. Just a blank window.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

I have "Open previous windows and tabs" and "Open Firefox automatically when your computer starts up" boxes checked in my settings.

Firefox is not opening automatically and my previous tabs are not showing up.

Thanks
