Firefox Support Forum

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

Dear Sir or Madame,

Read Aloud isn't working on Roshreview.com and other websites for my new macbook on Firefox but works on my old macbook.

It says "Missing host permissions for the tab"

I'm a student, which means I'm constantly accessing my university's library page. I've run into a weird URL autocomplete issue that I can't seem to resolve.

Beginning to type "library" in the URL bar leads to Firefox autocompleting with a past college's library site that I haven't used in years. It's not in my bookmarks, I've deleted all its site data in Firefox's history, I've tried the "shift + delete" trick, but nothing's making this autocomplete go away. It doesn't seem like Firefox Suggest, but something else.

All I want is for my school's library to show up as the autocomplete. It's so annoying to navigate away from a website I haven't used in years every time.

Any suggestions on how to resolve this?

I accidentally closed both of my Firefox windows with an "x" and the rebooted my computer. After the reboot there is nothing under "History"->"Recently closed windows" and "Recently closed tabs". Is there any way to get my windows back?

1) Firefox advertised free apps when you signed up for vpn. However, when I signed up for vpn, I didn't get any apps. Did I do something wrong? Why didn't I get the free apps? 2) I don't seem to be able to add the VPN two other computers. It seems to want to sell me (Again) the VPN. I don't want to buy it again, just add my existing VPN to other computers. 3) I have some Macs that run Parallel's. Do I need to add Firefox VPN do the Windows that is running on Mac. Or, does my Mac Firefox VPN somehow protect the windows without adding a separate VPN on windows?

Hey there,

Starting with Firefox v115, you had to set layout.css.page-size.enabled to false in about:config to get the page orientation back for printing PDFs (i.e. Portrait or Landscape).

It seems with the release of v119, this once again is broken and the layout.css.page-size.enabled setting no longer works. Is there something else that needs to be done now? We rely heavily on this and our current workaround is installing the ESR version of Firefox but seems like it'll catch up eventually.

Any help would be greatly appreciated!

Thanks!

I am told to disable pop-up blockers in order to have a payment verified. I do not know what pop-up blockers are, I do not know where they are. When I go to Settings and search for pop-up blockers, I am told "Sorry! There are no results in Settings for "pop-up blockers"; and instructed to visit Firefox Support. I have been sent on this circular quest three times now. Please help me.

Hi,

I have come across an issue where the Enhanced Tracking Protection (ETP) feature has stopped working on every single website I visit.

Every website I visit, the ETP icon is greyed out and not detecting any trackers.

For instance, when visiting the independent website, the ETP icon usually glows blue to indicate there are trackers. However, now, it is just greyed out, which is incorrect.

So far, I have done the following troubleshooting steps to fix the issue, but I have had no success:

• Uninstalled and reinstalled Firefox
• Signed out and signed back in
• Disabled and removed all extensions
• Cleared cookies, cache, history, site settings, etc.
• Opened Firefox in Troubleshoot Mode (with extensions disabled)
• Deleted my profile/files and created a new one

I have also checked this article: https://support.mozilla.org/en-US/questions/1327504

Can someone please help me with this, as I have no idea what else to do to fix this issue?

I started Firefox from scratch with a new profile, and the ETP worked for a short period, but when I closed and restarted Firefox, it just stopped working on every single site - this keeps persisting.

Any help would be appreciated!

I suffered a catastrophic crash and had to replace my computer, a mac. I replaced it with another mac.

Because the older one will not boot up, I could not migrate my firefox data.

I ended up doing 'lost password' for all my sites.

There are a couple where the lost password thing hasn't worked.

It occurred to me to rename the (new computer's) logins.json file, copy the old computer's logins.json file from my external backup drive, put it in new computer's /user/library/application support/firefox, and then look in preferences, get the two passwords I want, set things back, enter these passwords into firefox again.

This did not work. In fact, now no matter which file is named logins.json, preferences says I have NO passwords stored.

I cannot find anything that tells me how to just decrypt the .json files (at least, not in a step-by-step way that I can use.)

Never had an issue with my Gmail sidebar calendar loading automatically on Firefox. With the latest Mozilla update to 114.0.2 for my Mac, the calendar sidebar flashes the calendar icon but fails to load. The other sidebar apps are functional. I can load my full calendar in a new tab with issue. Signed into my Gmail account on Chrome and Safari and the sidebar displays as it should.

So I have the latest version of macOS Ventura, the latest version of Firefox, and the latest version of Roblox. Whenever I try to open a Roblox game from their website (yes, I know. Roblox now has the desktop app so you don't need the website to open a game), it opens the app, but not the link, which means it doesn't open the game :( Does anybody know how to get Firefox to open the link and not just the app? (Btw no hate on firefox)

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

Hi Mozilla community, I hope you can see the image i loaded. Have others seen this message? What is the fall out? Should I get Mozilla VPN? thank you so much!

hello I cannot turn off Firefox Fullpage Translation, which is really annoying. When I browse I get asked for every new page in which language I want to translate and I don't want to. The translations are mostly bad and I know in which languages I browse and research. I haven't been able to find how to turn it completely off in the settings. Can anyone help? It'd be great, thanks.

Hey all,

I have a few customers that use Firefox and the last month everyone has experienced an issue with tabs constantly crashing. Everyone is on the latest version and there really doesn't seem to be much rhyme or reason.

I've tried: -Doing a clean install -FireFox refresh -Disabling Extensions (we only use uBlock Origin) -New Profiles

Not sure if this is normal but there's nothing in 'about:crashes' after it happens (i assumed because it's just tabs and not the browser itself).

These are all Windows 10 machines.

Any help would be greatly appreciated!

Every time I do a search for services "near me" (hospitals, hotels, etc.), Firefox is using an out-of-date five-year-old location. Very frustrating! How can I change this? Anyone's help is much appreciated - I just haven't been able to find a link to help me fix it!

For some reason my Firefox on my Mac and Windows computer won't sync even though I am using the same account. I would like my Mac to look the same as my Windows computer. I have tried logging in and logging out on both, all the basic fixes but nothing has helped.

Thanks.
