Firefox 技術支援討論區

I turned on my computer like any other normal day this morning, except when I launched firefox it was like it was freshly installed, all my passwords, usernames, cookies, saved bookmarks, work related history material is all GONE it's like I just installed firefox for the first time. A lot of these passwords I dont know off the top of my head so I'm going to have to ask my business partners for ALL the passwords... Why did firefox do this? What is the problem??

I've got a persistent issue where Firefox immediately crashes when I open it initially.

Starting it again after this crash works totally fine, though if I close out and re-open a few times it will crash consistently (after every 3-5th-ish open).

It has been happening for the last year or so, and despite clean installs of the browser as well as other diagnostics it won't go away. It's incredibly annoying :(

Hoping the Firefox community can give me a hand and help solve this.

When I reply to emails, either reply, or reply all, I prefer to see all the email addresses from the email header that the original email was sent to. This is the default on most email systems I've used. I think it was the default on Firefox until recently.

Now, when I do a reply, or reply all, the message now starts with the original email, without the email headers. I understand some people may prefer that, but I definitely don't like it. It can be useful to see who the original email had been sent to, especially if there are errors in that list of people, or the people included are fewer or more than the previous email.

Note, if I forward the email, the email does contain the email addresses from the original email header.

This behaviour caused me some real grief when I realised some people had made a mistake when sending me an email recently.

Is there a setting to adjust this?

I've finally moved from desire to concept/name for a website I want to start. In the old days I had a couple of different sites through EFF in its infancy when it furnished this service and I knew the administrator personally. I then used a couple of different services such as GoDaddy (have no current domains registered). Can anyone direct me to a) a good place to go, b) where I should be asking this question instead of here  ??

I'm asking here because my computer guru of 30 years (Gale Rhoades) has passed away and I can't ask her anymore. She trusted Mozilla 100%. I am going to need help with docking(?), and with some kind of formatting/template system. The site will be a place for me to share my life hacks as late-life autistic with massive experience in low/cost-effective DIY health, gardening, fermentations, household management, companion animal management, crafty solutions, and all around life hacks, not just for autistics but for anyone. I know this is niche, but I just would like to get my knowledge base out of my head because I really do have a lot to share. If it could possibly generate some right-livelihood inputs that would be great but that's not my main goal. My main goal is I will die and everything I know will be lost, and what I know has been hard won and worth making available. I've worked with computers from the mainframe days, but I've never learned code.

All thoughts welcome on how I might proceed. Again, please direct me to a good place to ask/discuss.

Best wishes, --Victoria

Hello Before I reset my PC some months ago, I almost never had to Login to sites, as the kept me logged in. This no longer happens, and now I frequently have to Login to eg. my Google account which needs third party autho and all sorts. It is rather annoying having to Login to Google every time I close the Window.

I do not have this setting on: "delete cookies and site data when Firefox is closed" I do have this setting on: "Ask to save logins and passwords for web sites"

It does save my Password and autofill, which makes it easier. But it is still annoying, that I have to login to everything every time.

I have tried reinstalling Firefox, to no avail.

Please Help

I don't know but I'll say that I've tried using troubleshooting mode, cleared my startup cache, reset the browser and redownloaded the entire application. this happened after I cleared some stuff from my laptop don't know if that has anything to do with it though

So I I've been holding out upgrading to W11 for some time now, but have to upgrade after being tipped by a friend about ONE convenient feature for multitasking, split apps view and combining it into one tab. So far so good, didn't experience any issue. One complain I have is the gigantic cut, copy, open..etc Tab at the top of the new file explorer. But, again, nothing out of the ordinary.

But when I opened Firefox for the first time after upgrading I noticed a painful delay before actually loading the new pages. At first I thought it was only because I just recently updated the OS, so I leave for few hours and keep working my docs. After going back to browse I still have the same issue. This time I notably irritated because of browsing my regularly checked websites have so much delay now compared to before I upgrade to W11.

Here's the list of thing I tried to fix this issue.

   Clearing caches

   Disabling add ons

   Disable enhanced protection

   Refresh Firefox program

   Updating my chipset driver 

   updating my gfx driver

   Reseting my network.

Nothing I tried above worked.

Again the issue is not internet speed. When I downloaded the AMD drivers, it was 14MBps, quite fast.

Then I open the "task manager" and tick the "always on top" option. I noticed that Firefox is still idling even after I clicked links in my homepage. Firefox only uses 2% of CPU usage. It stays that way for 4-11 seconds (depending on the websites I tested) before eventually ramps up the CPU usage to the percentage I expected to opens a new website.

Anyone knows the answer? Please I'm getting desperate here. I don't want to daily drive chromium forks and would like to keep using Firefox.

I have an mid 2007 IMac running El Capitan 10.11.6 I replaced my old Firefox version with a newer incompatible one and now I can’t recover the old version of Firefox. All my bookmarks and saved data was on that older version. Can anyone help me find the most current version of Firefox for my Mac? Thanks!

I downloaded version 101.0.1 and lost most of my bookmark TAGS! These help me find things in my many bookmarks. I've kept version 98.0.1 in my Applications folder (MAC Mojave 10.14.6) and it still has all my TAGS intact. I can't copy / paste or drag and drop them. How can I transfer my bookmarks TAGS?

Okay, this is a weird one. I have been streaming the video feed from a .tv site for several years (I like to chat and discuss episodes with other watchers). Last night, the feed wouldn't load; I thought this may have been some slowness in my internet connection, so I shut my Windows laptop down and went to bed. I got up this morning and logged in, and the feed was doing the same thing (loading bar; three dots cycling over and over). I checked if there were any new updates for Firefox (there were not), and likewise any changes to the Windows codecs (all files are current). The rest of the browser (other open tabs) are working normally. Cleared the cache - same result. The feed was playing normally for the other site viewers, as I could see them commenting on the episodes that were currently playing. I then checked if I could access the .tv site via a different browser (MS Edge...ugh); and the site loaded and played normally. I checked it on my phone's browser; site played like it usually does. Hmmm... I then opened Firefox Private Browsing, typed in the site... and it's playing normally. Still nothing on my usual browser. Any Ideas?

I need an extension frequently but I can't put it in the toolbar, and I can't move it to the top of the Extension list. What do I do? Is there a config setting I can use?

I use firefox as my browser and to operate my 3d printers web interface, on my local network

with firefox the data that the printers display is very slow to update, for example if i input a movement command of say 10mm firefox takes at least a few second to display the number that corresponds to the movement change, its definitely firefox as opening the very same machine and sending machine commands in any other browser does not result in a data lag.

How to BLOCK systemtimezone detection in Firefox? Can this be done with firefox or with the operatingsystem itself? After all i know for a fact that the bromite android browser has this feature and it works. I noticed that disabling javascript blocks systemtimedetection, but it also basically renders the browsers useless for my purposes.. are there specific javascript config settings regarding systemtimezone detection? I really feel that when a website spys on my systemtimezone this is a breach of privacy as this goes beyond the browsers im using to view the website but instead directly access information about my system, im not ok with that... Using a virtualmachine just to fake systemtimezone cannot be the solution, this is ridiculous.

By the way, i hope Mozilla won't let down support for Manivest v2 ever, there is a chance firefox will gain a boost in users after google pushing Manivest v3 that hard... making adblock useless, what a shame.

Hello,

I've recently encountered a curious issue with my Firefox browser (Firefox version 102.0, Windows 11 Insider Preview 10.0.25145.1011). At seemingly random times it will freeze for between two and five minutes (roughly). UI elements become completely unresponsive and the cursor does not update when moving over the browser window. The window will not minimize. Yet, Windows Task Manager does not report the application as being unresponsive. While never a common problem, any freezes in the past would eventually cause the Windows Task Manager to identify it as unresponsive.

I have disabled "recommended performance settings" and hardware acceleration to no avail. Everything seems perfectly normal immediately before and after the freezes, and I've yet to identify how I can trigger them. I do not recall having made any changes to my browser before the freezes started occurring, though multiple Windows updates have taken place since then. If I'm too impatient to wait I will end the Firefox processes via Windows Task Manager and restart it so I can return to my tabs without having cookies deleted. I have 13 plugins mainly covering privacy/security concerns. Is there some sort of debug tool I can engage to see what's occupying Firefox while it's frozen? I've just found the Firefox Task Manager, and will see if it can offer any additional information during/after the freezes.

Thanks, Logan
