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 checked and borh of my Lenovo Chromebooks are running the 2026 version. Neither one will allow me to import bookkmarks . Is there a version I need other than the provided by Google?

bold textI have finally installed Debian 13, Trixie, into my computer. However, I don't seem to have attached to the Debian Mirror. How can I do that?

Hiii, I am using Floorp 12.16.3@153.0 on Debian 13 with KDE Plasma. Since the latest update, navigation from Floorp’s Private Container no longer stays inside the container.

Steps to reproduce:

1. Open a new tab in Floorp’s Private Container. 2. Type either a URL or a search query in the address bar. 3. Press Enter or click the arrow button. 4. Instead of loading the address in the current container tab, the browser creates a new regular tab outside the container.

The new tab does not show the container indicator and uses my normal browsing cookies. However, clicking one of the shortcuts displayed on the new-tab page correctly loads the website inside the Private Container.

I have already tried the following:

• Confirmed that `browser.urlbar.openintab` is set to `false`.
• Confirmed that `browser.search.openintab` is set to `false`.
• Restarted the browser.
• Disabled Floorp Start.
• Opened `https://example.com` inside the Private Container and then entered another URL or search query in the address bar. It still opened a new regular tab.
• Tested by pressing only Enter, without Alt or any other modifier key.

Expected behavior: entering a URL or search query should navigate within the current Private Container tab.

Actual behavior: a new regular, non-container tab is created.

This previously worked correctly and appears to have started after updating to Floorp 12.16.3, based on Firefox 153. Is this related to a change in Firefox 153’s container behavior, or is it likely to be a Floorp-specific bug? Please help, I'm a huge floorp fan :(

the top bar in the browser is so small it is hard to read and i find it difficult to access the icons. increasing the value of "layout.css.devPixelsPerPx" increased the browser text but did not affect the top bar. Is their another approach or is their a magnifier the will work. Thanks.

I sent an email a few days ago asking for a refund and a few hours later changed my mind, I couldn't cancel the ticket (as far as I know) so I sent a follow up email to disregard the first email because I thought it would just be more hassle and I think the VPN works fine anyway. Today I get an email saying my subscription had been cancelled! which I could understand is my fault for being indecisive in the first place and the last email I sent might not of been read in time, but the email that I had received also didn't state I would get a refund and seemed like an email I would get if I had cancelled my subscription myself stating "We’ve cancelled your Mozilla VPN subscription. Your final payment of US$59.88 was paid on 14/07/2026" Should I still expect to get a refund or was there an error with my request?

I run Ubuntu Mate. But versions later than 20.04 of Ubuntu Mate do not provide color support for my Samsung CLP-620. And, I can't install your latest MozillaVPN version on 20.04 because it requires libssl.3 (I think that's the designation) which is no longer available for 20.04. So, I am left with the choice of (1) no MozillaVPN but a color printer; or (2) no color printer but MozillaVPN. I have multiple computers so if you can't tell me a way to get both (MozillaVPN and 20.04), I'm stuck with a conundrum and will end up dedicating one expressly for printing when I need color -- what a waste!

Note: I know 20.04 is history but I can live with it if I have to rather than junk a good printer.

I hope you can help.

All the best. Thanks for all you do.

Hello everyone,

I would like to ask for clarification regarding the distribution of Firefox through third-party packaging methods.

As I understand it, Mozilla's trademarks and branding are protected, and in some cases official permission may be required to distribute Firefox under the Firefox name and branding.

Within the Ubuntu Touch community, there is a method called "Crackle" that can repackage existing applications and make them available as installable "Clickable" packages on the platform. One of the applications that has been repackaged in this way is Firefox.

However, this Firefox package is currently not available in the Ubuntu Touch software store because there is concern that distributing it may require explicit permission from Mozilla.

My question is therefore:

Does a project or community need Mozilla's permission to distribute a repackaged version of Firefox through a software store? If so, what would be the correct process for obtaining such permission? Alternatively, if the software is merely being repackaged to provide an installation method on another platform, without modifying Firefox itself, is additional permission still required?

We would appreciate any clarification regarding Mozilla's policies on redistribution, repackaging, and trademark usage in this context.

Thank you for your time and assistance.
