Firefox 技術支援討論區

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

Hello,

I just got a new Macbook Air and I am trying to sync my bookmarks and preference etc., from my current Macbook Pro. I read the help articles and one thing I cannot find is a "Sync Now" option on the Air. It is not under the menu icon list. I signed out of the Pro and back in. The user and PW are the same on both laptops. Hoping you can help.

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.

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.)

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 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).

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)

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.

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!

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!

Autoplay media blocking does not work. I've tried to block autoplay on sites settings and also done this about:config fix without results.

   media.autoplay.default = 5 [0:allow;1:blockAudible;2:Prompt;5:blockAll]
   media.autoplay.blocking_policy = 2
   media.autoplay.allow-extension-background-pages = false
   media.autoplay.block-event.enabled = true '

Videos still start playing in some websites. I've noticed that when reloading the page, then autoplay blocking works.

Example: https://www.iltalehti.fi/formulat/a/35242327-7699-45a2-a1b5-75ff330a9d13 When i go to page first time, it shows on the left of address bar, that autoplay function is not even enabled (no autoplay block icon). When i reload/refresh the page, then it shows that autoplay is disabled and autoplay block is working properly (icon appears).

So it's only issue when visiting the page first time, if page is refreshed, no issues.

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.
