Diễn đàn hỗ trợ Firefox

These are the pictures I get recently ... tiny. Micromised. Unsure if I accidentally hit a "micromise" button, but all of the sudden, the normal view became tiny.

Also, many a time by myself and others told: When browsing picture sites such as Deviantart, Pinterest, even Google Pictures, Firefox severely slows down up to even dead stop after a while. Though several versions have passed, this issue still remains.

Clearing Cache, or using DelTempDir/FlushDNS doesn't help at all, once it begins to slow, only full restart of FF helps, but this ain't always an option. It almost seems that the memory is filling up by the feeds of these sites, and just cannot be cleared, no matter what.

Using a Memory tool ALSO runs nowhere.

Please assist?

Thank you.

Is there any way to turn off the button "Open video in a new tab" that appears when you hover on an Instagram video? This button is blocking a button from an extension that I want to use.

Hi,

Firefox issues warning while accessing websites which are signed by Internal CAs. However, we could see the same website working fine with Microsoft Edge, Google Chrome, etc.

Firefox work fine while accessing websites which are signed by Public CAs. The issue is only with websites signed with internal / Private CAs.

Below is the error message:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to "XXXX.XXXXX.com". If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

I am trying to move my mobile bookmarks from Firefox to Brave. I've synced them with no trouble from Firefox Android to desktop. I can see a folder in the Firefox bookmark manager called "mobile bookmarks", and it contains all my mobile bookmarks. From there, I can open them in Firefox, Brave, Edge, and Chrome. No problem.

When I click "Import and Backup", then "Export Bookmarks to HTML", I'm able to save the HTML file to whatever location I like - desktop, Downloads folder, etc. However, when I go to open the file, it only contains the Mozilla default bookmarks. None of the "Mobile bookmarks" folder is visible. The HTML file is only 11 kb.

Screenshots are attached. Using Firefox version 113.0.1.

FWIW, I've also tried directly importing the bookmarks to Brave using their import feature (not using an HTML file), and Brave does not recognize any bookmark files whatsoever from Firefox. Getting really frustrated.

Is it possible for Mozilla to add a setting to Firefox that blocks .zip and .mov links from ever opening even if clicked on since a big part of the .zip links are being used to infect computers with malware

Hi there I love FireFox, after years of others recommending, I finally switched and really appreciate so many great features (automatic downloads not at all though). Anyways, I have a Tivo with in house and out of house streaming to Watch Tivo web app and Tivo android app. Until recently, was able to stream anything from Tivo Box throughout house. Android app works awesome, but no longer working on FireFox (or Edge & Chrome) Research shows this is due to a change in website security which is maybe similar to FF issue?

Chrome offered advance warning/remedy..as detailed below....

I am hoping FF team can rise to the challenge and get tivo online working again for the millions of us who still use and love our Tivos.  Or maybe another Tivo fan has a workaround they can share? I sure hope so, I have wasted hours already troubleshooting and hair pulling :(     Any and all assistance appreciated

Access to XMLHttpRequest at 'http://(MYIP):49152/sysinfo/json/svcinfo' from origin 'http://online.tivo.com' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `private`.

After researching that i found this link Chrome CORS error on request to localhost dev server from remote site

it went into a bit about how "Chrome has implemented CORS-RFC1918, which prevents public network resources from requesting private-network resources - unless the public-network resource is secure (HTTPS) and the private-network resource provides appropriate (yet-undefined) CORS headers."

So basically a public network "online.tivo.com" cannot access my local network (where my tivo is) due to this new CORS-RFC1918 standard.

The is a fix to disable this behavior for now chrome://flags/#block-insecure-private-network-requests

Need some help with Firefox crashing. System: Windows 8.1 64 Bit instilled on a Samsung SSD, 24 GB free space, 24 Gigs RAM, Firefox installed on conventional HDD (G:\) drive, 1.03 TB free space. This has been the standing configuration for many years, working with no problems.

Problems began with FF update 111.0. Any attempt to download files (.jpg or .pdf) would cause the “save” button to freeze, and after a seconds FF would crash. If an attempt was made to change a setting FF would again crash so quickly it was impossible to attempt any changes. Oddly enough, FF update 111.0.1 fixed the issue (or so I thought) and things returned to normal. I assumed whatever caused the problem had been fixed.

Unfortunately, every update beyond 111.0.1 reverts back to the same freezing and crashing behavior. I have attempted the following with all updates above 111.0.1 in an effort to correct the issue. So far nothing has worked. BTW, Brave and Chrome work just fine.

Cleared out all cache and cookies. Changed download folder Opening in safe (trouble shooting) mode Clean install(s) Disabled hardware acceleration. Putting the entire program on C:\ drive (apparently the newer FF installer does not allow custom installations any more). Checked and updated all drivers

Currently I have disabled automatic updates as none of them have the same freeze/crash issue. I am out of ideas and would certainly be glad to get any advice. At this point Brave is going to be my new default browser. Yes, I know 8.1 is no longer supported but I am not in a position to replace this PC at the moment.

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

I bought a new laptop. I installed ZoneAlarm and Virus Protection for Windows 11 as I thought Maybe Wolf and Windows Defender might be the problem. I did everything suggested by Mozilla to get it to let me log on. To no avail.

I did everything. I still cannot get access to https://www.chewy.com - despite my logging in many many times. Please tell me how to fix this. This is STUPID!

This is the error message I keep getting: Access Denied You don't have permission to access "http://www.chewy.com/app/login" on this server.

userChrome.css

the css is;

1. sidebar { min-width:34px !important; max-width:34x !important; }

appreciate any feedback because there seems to be an issue with the above

When I right click a tab I do not get the option to "Send Tab to Device" that I am used to on Windows. Is this missing from the Linux version? Or is there a setting for it?

I have searched the internet for this problem and could not find such things. I would appreciate any help!

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

My e-mail address changed, but the old one keeps popping up. I need to ELIMINATE the old one and use ONLY the new one. I've told various organizations, businesses, etc., to make the change. I want Mozilla Firefox to ELIMINATE the old one and use ONLY the new one. Help!

This is the last time I'm going to inquire about this topic. I will switch browsers bc Firefox touts their superior product with hundreds of complaints I just cant ignore further.

I USED to be able to close Firefox browser with confidence. Now I can expect to waste several minutes a hour/day logging back into my websites bc Firefox no longer remembers my login information..

I want ONE thing from Firefox, step by step by step instructions on how to put your browser back to the way it was before you'all decided to to "make things better".

my deepest regrets!!

Logged into Twitch, can see and type in chat, but video and audio do not work. This happens on my Main Twitch account as well as my alternate. I do not have this issue with Google or Edge.
