Firefox 技術支援討論區

Until recently my browser accessed all the sites I have used for years and now I cannot access them. As an example the message I receive is "You don't have permission to access "http://booking.jetstar.com/au/en/booking/select-flights" on this server".

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

I "upgraded to V90. since then, the URL box is highlighted red/grey stripes. The robot head icon is now in the URL box and it says "Browser is under remote control (reason Dev Tools). I've gone in about:config and set all variables to False, yet they reset themselves to true every time. How do I disable the DevTools. Thanks

Very similar to posts in previous years that are archived and largely unanswered or not up-to-date.

I opened up my a Firefox session to find out I was logged out of sync and when I logged back in all my passwords where erased.

This has been stable for the last 10 months and Firefox has provided a reliable password archive with nice syncing features. However, this is a deal breaker, since I cannot loose the login credentials randomly.

No updates. No conscious logging out. No disregarding warnings etc.

Anyway to revert or retrieve?

This post is on my Mac Catalina. This morning Firefox updated on my Windows 7 before I closed out. Now that it is evening Firefox does not open on that computer. What should I do to fix it since it does not open; it crashes immediately.

Hi, If you are not familiar with Medium.com, this site claims to track the reading time of a subscriber/reader when they read an article from Medium through a browser. This question is very important because the author of the article gets paid based on that person's reading time.

Given Firefox's privacy initiatives, I was wondering if Medium can in fact track a reader's reading time if the reader is using Firefox to view the site in a Private Window or tab? Does it matter if the reader blocks all the site's cookies with a cookie blocker?

Today I tried to place an online order to pickup from Texas Roadhouse, but no matter what time I chose a message said it was not available. The only selection that worked was "Earliest Available Time". Finally I called to place an order. Firefox worked 2 months ago but I don't recall which version I was using at the time.

Today I was using FF vers 97.x and later updated to vers 99.0.1 figuring that might be the problem, but it made no difference.

Later I tried Windows 10 Edge & that worked. Then tried a Chromebook & that also worked.

I've also had problems going to the Tracfone website & so have several other people. It's hit or miss with Firefox & usually it doesn't work. But Chrome or Edge seem to work for everyone.

Is this a website problem or a FF problem?

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

version 94.0.2 (64-bit) message: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I can not see any of my bookmarks and I can not bookmark any page. I have: Shut down Firefox and restarted: no help uninstalled, deleted folders, and reinstalled: no help Import bookmarks from another browser: no help. That doesn't work either

What "security software" is the message talking about?

Hope you can help, because I don't want to go to another browser.

HI After using Chrom for num of years I have now reverted (upgarded!?) for Firefox. However what's casuing me to regret my decision is the layout og Gmail in the browswer. Most of the labels and text are surround by a white Highlight or box which looks ugly. I have exhauste dverything I know to get the text to look like Gmail in Chrome with no success. See attached screen shot of comparison. Could you please give some idea so That I can stay with Firefox Kind regards Chris

i restarted computer and firefox did a software update. once done, and firefox reopened i am missing the bar that had various websites I frequently use below the address bar. for instance, mail, suddenlink, siebert, etc etc . How do i recover that?

I added a plugin that enabled privacy.clearonshutdown for a number of settings and I have lost my Cache and History. Is there a way for me to restore that data? I haven't restarted my computer yet.

I was looking at other options: https://support.mozilla.org/en-US/questions/1290163 and apparently there is an index.dat thing I could use as well, but I can't find it. I really can't afford to lose yet more data after my last mistake.

French expat in Asia I noticed that since the launch of this free website, Firefox 93.0 running with macOS Big Sur 11.6 is unable to connect properly with the French TV5MONDEplus website. Access to the site is entirely possible but the connection seems to stop as soon as you try to view the programs offered… This problem doesn't arise by using Chrome.

Greetings... I would like to increase the font size in right click menu box in FF 89.0 (64-bit) (see attached png)

I found a similar 2018 query here at: https://support.mozilla.org/en-US/questions/1241117#answer-1174375

and based on that exchange I added the following to userChrome.css file

/* FONT SIZE IN RIGHT CLICK MENU BOXES 5/1/22 */

1. mainPopupSet menuitem,
2. mainPopupSet menu { font-size: 16pt !important; }

/* */

I closed and reopened FF. This change has no effect on the menu font no matter what font-size value I enter. Have I done something wrong?

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?

I'm using Firefox 104.0.2 (64 bit) under Windows 11.

Under Settings I have selected Startup Open Previous Windows and Tabs.

I normally have more than a dozen tabs.

For the past few days, when I start Firefox my previous session is not restored and I just get the single Firefox tab.

When I got to History there is no longer a Restore Previous Session option.

How do I get it back?

Thanks

Ok, so I installed Firefox today, and tried to watch Discovery+, it kept saying it was installing components to play the audio and video and never seemed to actually install them. I finally figured out it's the widevine plugin sitting there with a yellow bar saying it's going to install soon but never does.

I went through nearly an hour of troubleshooting, and nothing has worked. I tried toggling the DRM option on and off, restarting the browser and PC, reinstalling Firefox, restarting my modem, disabling and enabling the plugin itself, going to all the streaming sites I use, attempting to manually install the plugin, etc.

As far as I know, I'm not using an antivirus, I don't have my VPN on, any other extensions or plugins, pihole, or anything else I saw in other support queries. I'm just going crazy trying to fix this since it seems nothing works.

As I belong to no organization, I find this disturbing. Some of the settings being "managed" for me are not as I want them. How do I get access to them? FWIW. I am using Firefox in Linux Mint. Thank you for your help.

On some websites (e.g. the Guardian newspaper) Firefox displays graphics overlaying the text, making the page unreadable. Same page works fine in Chrome. Thoughts?
