Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

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.

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

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'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 🤮

Hi

OK so I was having some issues with firefox where I had to reinstall it and this did in fact resolve the issues I was having.

Problem I have is this though when I reinstalled it I first backed up my chrome folder which had all my custom CSS to move the tabs to the bottom of the header area and when I then reinstalled FF I then copied the folder back into my profile folder using the More Info under the help menu to make sure I was in fact in the right profile folder.

Problem is the code isn't moving the tabs and I seem to remember some issues with this the last time we had to fix FF that something had changed with the Chrome folders and such.

So what do I need to do to get my tabs back on the bottom again as I hate them up top!

Version: 128.0.3

Thanks!

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

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.

Hello. Recently I've noticed video quality has been reduced on amazon prime video. I get a message saying my hardware doesn't meet HDCP requirements.

I've already tried playing the same video on edge, and the quality selector was fine there, full HD video.

Thank you in advance

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?

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

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'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

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

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.

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.
