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 🤮

Hello. I have a problem with turning off google safesearch. I'm 28 years old so it's not a problem with google acc. I have same firefox on pc and on laptop. On pc and on smarthphone it's easily turning off and if i'm using edge or chrome on laptop it's also turned off, but if i'm using firefox exactly on google it's always turned on no matter what i'm do. Just in case, if i'm using for example bing search in firefox it's also turned off, likely it's always turned when i'm using google with combination in firefox. Methods that I already tried: 1) Turned off in computer settings (not worked) 2) Reinstalled browser (not worked) 3) Checked in my wifi settings (not worked) 4) Updated everything (not worked) Waiting for your help.

With the new 118 version that introduced fullpage translations, whenever I got to a site that's not in English and that is one of the supported languages, the translation icon doesn't appear at all in the address bar. I can go to the menu and click "Translate Page..." and then the icon will appear but when I click to "Show original" it dissapears.

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.

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

Hi,

Is this new feature? Once I click on link with middle mouse button, that tab is opened and switched to it. Previous firefox versions only opened tab and thats it. It is very frustrating. I want open multiple tabs and then view those tabs. Now I have to, suppose I have 5 links listed in webpage:

I middle mouse 1st link Then I have to return to my previous page I middle mouse 2nd link Then I have to return to my previous page I middle mouse 3rd link Then I have to return to my previous page I middle mouse 4th link Then I have to return to my previous page I middle mouse 5th link Then I have to return to my previous page

If it is new DEFAULT, then please make ant option to switch back in about:config, thanks!

I recently added the "Display Autoplay" extension. I can't seem to figure out how to get the icon to show in the tool bar. See Attached acreen shot. That's assuming that this extension icon can be added to the tool bar. I look forward to anyone's comments. Thanks

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

Any help, appreciated.

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.

Hi

I've been having an issue logging into Gmail using Firefox. I've used both Gmail and Firefox for years and have never had a problem, but I now get stuck in an endless loop on the Gmail login page. I select my account, enter my password, then get sent back to the account selection page.

The problem seems to be relating to me trying to link two Gmail addresses so that mail from one is forwarded to the other. I set up one account this way without any issue, but when I went to do it with a different account, I got an error code. After that, I was logged out of Gmail in Firefox and haven't been able to log back in.

Things I've tried so far:

• Using a different browser. I can log in without issues in Chrome.
• Logging in with a different method. Neither my password nor my passkey work.
• Logging in with a different Gmail account. All of my accounts seem to be stuck in this way.
• Disabling all my extensions. This doesn't help.
• Clearing Firefox's cache. No luck here.
• Restarting Firefox and restarting my PC. Turning it off and on again doesn't fix it.
• Contacting Google support. They said they think it's a browser issue as I don't have any problems using Chrome.
• Using Firefox's private browsing mode. This does work and I can log in to Gmail. However, I don't know exactly what the problem is because I've disabled all my extensions and cleared the cache in regular browsing mode and still can't log in that way.

So I have a partial solution (using Firefox's private browsing mode) but it's not a long-term fix. What else can I try? Has anyone else seen this problem before and been able to fix it?

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.

In the last week or so, iPlayer, All4, and Spotify (that I know of) have stopped working in the Firefox browser. All4's error suggests DRM isn't enabled, the others just say try again. Roll20 hasn't been working for even longer (more like months). They work in Microsoft Edge and Chrome. Youtube is still working, as are video players in social media.

I have tried the following solutions:

• Firefox is up to date
• Windows is up to date
• Updated graphics drivers
• 'Widevine Content Decryption Module provided by Google Inc.' is set to 'Always Activated' and is up to date
• 'Play DRM-controlled' content is ticked in about:preferences
• Checked if anything changed if either of the above were turned off (it did not)
• media.eme.enabled is set to true in about:config
• Put Firefox in troubleshooting mode
• Turned off my addons (including uBlock Origin) manually
• Tried in a Private Browsing window
• Turned off Tracking Protection
• Restarted my laptop

Nothing has fixed the problem, or given me any more indication of what is wrong. I don't know how to a) fix or b) find the problem. All I can think is that it may be related to the recent changes to Chromium regarding ad-blockers? But no one else seems to be having the same problem so I doubt it.

I have tried to disable hardware acceleration, refresh firefox, reinstall, and nothing works. It hangs every single time when searching on google or connecting to websites. This really sucks because I have used firefox since the beginning and don't want to have to stop now..

Hello,

This has been very challenging for more. I have searched the internet forms I cannot find the solution to this issue, please help! When I first bought this computer I tried to install Firefox it crashed and said that there was another instance of Firefox running. Now I tried again to reinstall Firefox and I am getting a new error, which is: Your Firefox profile cannot be loaded. It maybe missing or inaccessible. I followed one of the forms on this site. I did all that was in the form, IE: I tried to recreate profiles through the profile manager. I also tried to clear the cache in the cache folder. I also tried to move the profile folder via the profile manager. Nothing has worked. Please help me I am very disparate. Also so if necessary is there a way to get live support. thank you :)

I've always liked the Firefox New Tab page, with Pocket, and until today, DarkReader plugin has always worked. But now it says that it can't because the page is protected.

I tried the solution to use bookmarklets, suggested in https://support.mozilla.org/en-US/questions/1350781, but it didn't have any effect (https://sanketmehta7.github.io/DarkMode-JS-BookMark/

If I can't find a solution, I'll just ditch Pocket, and use Google as my first page, or something. Or maybe ditch Firefox, which doesn't seem to think that dark mode is important. I don't like being blinded by the light.
