I'm having a pretty frustrating developer experience using Firefox to help develop an app that uses Server Sent Events. Now, I'm not sure if I'm the one at fault or if it's something to do with Firefox itself (most likely I'm missing a config option somewhere).

Anways, the issue I'm having is that I cannot seem to be able to see Server Sent Events in the network tab of dev tools. This is specifically what I'm looking for: https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/inspecting_server-sent_events/index.html

I'm testing this functionality by going to https://sse.dev/testpage.html, opening my network tab. I can see the connection to the SSE endpoint however, all I see is "No headers for this request" or "No response data for this request". I know it's getting the data through the event source because I can do stuff with the data. I've also tested this in Edge and everything appears in their network tab as expected which, makes me feel like this is more of a browser-specific issue. Again, I feel like it's me missing a config somewhere or having a privacy setting set which is somehow messing with the event stream.

Any help is appreciated... I guess I got to use Edge for the time being 🤮

I've spent many hours trying to fix this problem. When I click on a document that I want to view, it is downloading to my computer. I have the latest version of firefox on a windows 11 pc. Please assist.

I have Firefox Browser version 112.0.1 (64-bit). Firefox says that there is a new update. In order to install the new update it is required to have Administrator privileges in the computer. Until now, to update Firefow, Administrator privileges were not required.

So I have a video playing on firefox, but the moment it drops from the foreground, it immediately pauses the video (the actual video playback). The audio continues, but the video stops until it is back in the foreground, at which point the video continues where it ought to. I have tried disabling the unload tabs in the config menu as well as disable the foreground pausing or whatever its called, as recommended by previous posts. I used to not have this issue at all, so I'm not sure what changed. Please help! Thank you.

Every time I open Netflix in Firefox browser, to watch streaming movies, it won't show them but keeps taking me to a page asking me to log in again or pay for a Netflix account. (attached) I already have a Netflix account and can watch streaming movies with no problems on other browsers, but not using Firefox, which is my Default browser.

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

My browser could only display the standard system fonts (such as Microsoft YaHei and Consolas), but not the fonts I installed. I was getting 'Request for font "xxx" blocked at visibility level 2 (requires 3)' from the console on every website that tried to use my local fonts.

The problem appeared in obstacle removal mode, but didn't appear in the latest stable Firefox release.

Version: nightly 120.0a1(20231006152733) System: Windows 11 22H2 22621.2134

English is not my first language, so please forgive me if it doesn't make sense.

UPDATE - - problem solved - - Using Firefox Troubleshooting Mode I found that the problem was ''''caused by an added extension '''' which has been turned off (I hope) One thing I don't understand though is that I fixed this in Firefox but it also fixed it in Chrome. All images show up in both, so how does one browser fix a second browser? I have yet to check Safari but I never use that one anyway, so I'm not going to push my luck! Thanks Terry.

- - - I have a LOT (hundreds) of images that do not show up on many pages and each one is labeled,

403 Forbidden in the Network Monitor.

There are images that do show up on the same pages and the amount varies.

Those are labeled with a green 200.

What causes this and how can I fix it so they all show on the pages?

and do I have to fix each and every one? That would take months.

Thanks

Recently I did a full scan with Microsoft defender and it detected a file in the “firefox/profiles../cache2/entries” as a trojan:PowerShell/Meterpreter.A (And also something related to gzip I’m sorry that I didn’t take a screenshot of the message but I completely freaked out and deleted it immediately after scanning with the other AVs). I installed malwarebytes and Avast and did a full scan they returned with a no malware has been detected. In the moment I panicked and immediately deleted the file (I should’ve uploaded to virustotal to see its behavior and what it can do and change to my PC if it is indeed malicious). Then I did a full rescan using Microsoft defender and it returned with a 0 threats found. However, I only went to a couple of websites recently which as far as I know are safe such as msi, cpuid, I don’t go to shady websites plus I have ublock origins as an Adblock. My question is as follows how much percentage wise this Trojan is a false positive and if it is a virus how much damage it did (the thing that got me freaked out is that it’s a meterpreter)

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

Since the penultimate and now the last current update to version 127.0.2 (64Bit), the button (tile with the + sign) to add new shortcuts is no longer available. How can new shortcuts be added now?

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

Since the last Firefox update I have been unable to login to my bank's website. Attached is a screenshot of the message that appears. As a test I tried logging in with Google Chrome and was successful so it is likely something with the last update of Firefox. Note that I am using Windows 7 and do not want to change to a newer version.

I am experiencing issues with my ChatGPT subscription while using it on the Firefox browser. Despite having an active subscription with access to ChatGPT-4, the interface only shows an 'Upgrade' option instead of the 'Refer a Friend' feature, which suggests that my subscription isn't being recognized properly. Additionally, whenever I try to send a message in the chat, I receive an error stating, 'Our systems have detected unusual activity from your system. Please try again later.' I haven't encountered these issues on other browsers. Could you please provide assistance or guidance on how to resolve these problems with Firefox?"

I have tried to clear the cache, and relogin, does not work...

I am wondering if this is an issue of Firefox or ChatGPT, any resolution on this?
