Diễn đàn hỗ trợ Firefox

I have used Firefox as my primary browser for many years, and have always used autofill for my passwords, credit cards, and addresses. Suddenly, about two weeks ago, my credit card data stopped autofilling. When I go to Settings > Privacy & Security, there is nothing regarding autofill anywhere (or anywhere in any Settings). I have attached screenshots of my entire Provacy & Security page, as well as Settings searches for "autofill," "payment," and "credit card." Please help me figure this out ASAP, or I will have to switch to Safari as my primary browser, which I don't want to do. Thank you!

On Galaxy 23 Ultra using Android 14 & Ui 6.1 w/ Firefox, my Bookmarks disappeared. How do I get them back? Tried about:profiles, but nothing comes up. Recently due screen going haywire, phone was reset & the shop left me with Google, which I hate. Have been things getting back to Firefox I've used for years. Not sure if lost then. Bookmarks screen/setup I get, must be Google's, because it's not like FF's. I have Samsung & Google backups, but didn't realize Bookmarks were not put in them. Phone & apps are kept updated. FYI if it matters: Due to storm damage, I'm without a computer that might help. Help, pls. I'd be very appreciative.

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

I use a website in the UK alljigsawpuzzles.com The page loads fine and freezes with the firefox browser. Other browsers work fine. I have been unable to determine if a setting is the problem. I use https only. When I removed this setting, it allowed me to scroll for a few seconds and then froze again. Do you know what the problem is? It's true they recently upgraded their website. Is there a setting I need to change? Thanks! All updates are up to date.

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!

Hello,

Since the latest update of Firefox (version 135.0.1) when writing an e-mail the lines keep dropping down automatically at random intervals.

The e-mail host we are using is Polaris Mail, which is through our website provider.

To make sure it wasn't an issue with polaris mail, i have logged into our emails through microsoft edge and they have worked perfectly fine.

I have attached a picture for reference.

Kind regards

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

Why does my context menu show everything in the world? How can I change this back? did this come with an update? most of these options don't work, even the simple "save image as" function

I've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

I keeep a file on my system which is essentially an annotated list of links to useful references. Since upgrading to Firefox 135.0, I can no longer open links to these references if they are local documents (links to websites work fine). Attempting to open a local document (usually an .odt file) brings up a window describing the file and offering tp save it, or open it with the system handler. Opening with the system handler produces an error message "unknown error" and suggests trying saving to disk first. Clearly Firefox does not know how to deal with .odt files, and I can find no way of telling it.

If I get to Settings - General - Files and Appications and scroll down the Applications window to ODT document, I find it set to "Always Ask". I can change this to "Save File", "Use System Handler (default) or "Other". "Save File" is not what I am trying to do, and the other two options produce the same result as "Always Ask". There seems to be no way of telling Firefox to open .odt files with Writer (or anything else for that matter.) The support page (https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file) suggests that I should have a further option "Use<application name>". But it just does not appear. Anyone any ideas?

Is the Primary (formerly called "Master") password shared or Firefox synchronised between different devices?

The reason that I ask this is that I am a decrepit and ignorant old bugger in his 8th decade that has been using Firefox for nearly 25 years. Consequently I have a lot of passwords stored in Firefox's password manager that I REALLY do not want to lose.

Unfortunately, on my main desktop machine, becoming more paranoid after a suspected identity theft attack, I decide to change the Master Password (recently re-named to Primary Password) to something longer and harder to guess or break.

Unfortunately I have forgotten what I changed it to ! (I can remember the first 15 characters but then not the ending sequence...)

However, I discovered that on an old laptop (that had not been connected to the internet for a long time - and I've disconnected it from the local Wi-Fi now) that my old password still worked and I could still see many of the old passwords (since it had not been synchronised).

I am worried that if I try and restore my passwords by now connecting to the internet and synchronising, I will then be locked out of this remaining treasury of my passwords if Firefox synchronisation then disastrously changes the old password (that I still remember) to the new password that I have forgotten - hence my question...

PS: I still have a paper record of something called an "Account Recovery Key" consisting of 8 groups of 4 alphanumeric characters (each group only contains capital letters and numerals - although one 4 character group does not contain any numerals at all, but all groups have at least one capital letter). Could I use this to recover the misremembered new password?

PPS: Don't you think it is always a bad idea to include both zeroes and letter Oh for Oscars in this account recovery key as capital letters rather than lower case letters, since they look so similar?

ie z00 or zoo is less prone to confusion that Z00 or ZOO

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.

I had to re-instal Firefox because I had problems with the latest update and now there is no fox icon top left hand corner and no file, etc., so I cannot send email link, print, etc. I would love for someone to assist me.

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?
