Diễn đàn hỗ trợ Firefox

Hi, I'm a Firefox user since around 2004. Whenever I used FF i always opened multiple windows of FF. At some point Mozilla came out with Tabs. I don't use them and as a matter of fact I use the option under settings to open links in a new window (not tabs). Always have, Why? Habit I guess from the times I first starting using FF. I seriously don't use Tabs. I would like to Remove the Tab Bar from FF because of this reason and it frees up a lot of visual space on my browser. I've spent hours reading/searching/trying on "how" to remove or at least hide the Tab Bar. Waste of time so far, so I decided to Post the Question.

How Do I Hide or Remove the Tab Bar in FireFox?

Thanks For Everyone's Help in Advance:-)

Where can I get Firefox 52.9.0? There was a list of old versions here but now I can't find it. I found https://download2.portableapps.com/portableapps/FirefoxPortableLegacy52/FirefoxPortableLegacy52_52.9.0_English.paf.exe I really did not want the portable version but avast considers it a threat so it may not be genuine.

I need to install a browser on a Windows 7 laptop that I'm trying to get operational so the files / data can be migrated to another platform. I would like to use Firefox if possible.

I'm thinking I would need a prior version. If so, what version should I choose and where do I get it from?

The current / legacy browser is Brave but that has been disabled by installing Bitdefender as part of the ongoing cleanup process. --Thanks

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Hi All,

I would like the content area of my tabs moved up so that the box is filled with the actual tab color, without the white background, and also the text will be vertically centered. Right now, the text is dropping too close to the bottom of the tab.

Had this looking very nice in FF 88 with the same code, as you can see in the attached images, but it seems to render differently in FF 115 ESR and FF 125.

Below is some code I used to style the tabs, but the problem exists without this code as well.

I've also included some "tabs on bottom" code I'm using as well at the very bottom.

Would sure like to get those Classic Toolbar Buttons working again too (shown in the second image), but that will be a later request :)

Any help is appreciated.

Thanks!

After watching this video https://www.youtube.com/watch?v=mAfY_bNJTBI i went to https://www.cloudflare.com/ssl/encrypted-sni/ and did the test. Result is 3/4. (See screenshot below) Secure DNS, check DNSSEC, check TLS 1.3 check Enrypted SNI, fail In Firefox i tried doing exactly what the person did in the video but i dont have the settings he is showing in about:config Why is that? (Below you can see the screenshot, those settings are missing from about:config)

So my question reamins simple, how can i enable Enrypted SNI in Firefox?

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

I access a CCTV Network Video Recorder on the same private/LAN that I'm on using an PC via HTTPS. It's been working fine for nearly a year. Recently it won't access via HTTPS any more with the Error Message "Secure Connection Failed An error occurred during a connection to 192.168.1.30. Certificate key usage inadequate for attempted operation. Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

I've contacted the vendor but they seem at a bit of a loss. I can connect using HTTP, and an Android App (spit) still works too. I did find a Stack Overflow article from 2020 mentioning a possible corrupt cert9.db and/or cert_override.txt files, but as it's so old I wanted to ask for further advice before I start hacking things around. On another PC using the same browser version on the same network I get the attached response, not the same as the one I get and it will allow me to accept the risk. Can anyone help please?

Hello!

I have been using this userChrome.css code to hide the tab bar if there is only one tab (on Windows):

tab:only-of-type, tab:only-of-type + #tabs-newtab-button {

   display: none !important;

}

#tabbrowser-tabs, #tabbrowser-arrowscrollbox, #tabbrowser-tabs > .tabbrowser-arrowscrollbox {
   min-height: 0 !important;

}

Since one of the recent Firefox updates, this code does no longer work. Maybe because there is a new element in the tab bar: A drop-down list at the right.

Any idea how to make the above code work again?

Hello,

I am desperately trying to recover lost tabs from Firefox Browser after 2 crashes, freezing and forced shutdowns. I need the tabs for my work, and as usually happens, this has occurred at a time when I'm running to meet a critical deadline.

I've tried going to history, but the "recently closed tabs" option was greyed out:-( I've tried searching for other solutions, but cannot fine any that fit my situation. I'm not an IT expert - I know my way around what I need to use (i.e. professional worker), so clear & simple explanation would be much appreciated.

Can I recover the lost tabs from backed up data or a previous system image? My system is Windows 7, and I'm currently running Firefox version 115.0.2. All suggestions welcome!

Thanking you in anticipation off prompt assistance, MLH

Hi Everyone, My Bank has suddenly decided that ALL cookies must be allowed before letting their customers in -- a requirement with which I wholly disagree. My FireFox is set to block anything that moves, and supported by Ad Blockers and Ublock too. Is there a way in which I can configure FF to allow me into the Bank site without having to change my "secure" settings every time? I am no computer genius - so please make it simple for me.

Thanks everyone.

Ian

Since the last Firefox update I have been unable to login to my bank's website. Attached is a screenshot of the message that appears. As a test I tried logging in with Google Chrome and was successful so it is likely something with the last update of Firefox. Note that I am using Windows 7 and do not want to change to a newer version.

When using the Export Logins feature to create a .csv file, the last few fields don't seem to translate into any known date-stamp format in Excel. The data seems to have relative chronological value, but I can't make sense of it in a spreadsheet.

Can a developer check this and modify the output of those fields so it's more compatible?

Example:

 Header             Cell data
 ----------------------------

timeCreated 1675178753239 timeLastUsed 1684763722184 timePasswordChanged 1675178753239

A friend has passed away and I cannot access her obituary page. I could for a couple of days but I can't any more. Is this a problem with the FF latest upgrade? The page is [link removed by moderator]

I do not want her obituary page made public on a forum in case it causes inappropriate comments.

I have just discovered the page works ok on Chrome so I will use that for now, but I am reporting the problem to try and help you. I am using latest version of Firefox.

I have added a screen snip of the part-loaded page.

I just followed the button below about extra troubleshooting information and lost all the information I had typed into this box, which irritates me as well.

Have a look please and let me know, thanks.

Hello, today I decided to create a new Firefox Profile. I set the directory of this profile to be my desktop, which is where I usually put things (downloads and such) by default. I thought it would create another folder there on the desktop and put everything inside that, but instead it put a bunch of junk on my desktop. No big deal, right, I can just delete the profile, and that other junk should also be deleted. Well, not only did deleting the Firefox profile delete the extra junk that was created while making the profile, it also, for some reason, has deleted about 90% of everything else on my desktop as well. There are now only a few seemingly random things left on the desktop, that it decided to spare for whatever reason.

Where did everything go? The recycle bin is empty.. Most of it was just shortcuts, not a big deal, but I did have a few folders with some rather important work that I would very much like to retrieve. Please tell me Firefox didn't just nuke my desktop, and that all of those things are now unrecoverable? Windows 7 64 bit

Thanks very much.

Zoom.us renewed their DigiCert Global G2 TLS RSA SHA256 2020 CA1 certificate on 03/31/2023 and I now get a persistent error message (Error Code 6: ... certificate is not trusted.

Since then Zoom has not worked for me and their Artificial Intelligence says to open my browser and check my internet connection, time settings, updates, reinstall everything etc. - the usual responses ...

Zoom responds with "Error code: 6" and/or "Error code: 100068000"

 but do not stipulate whether these are Zoom Error codes or certificate error codes.

The Artificial Intelligence insinuation is that FireFox is not trusting this certificate.

Is this something FireFox can help me with? Perhaps, how to make this certificate "trusted"?

Thanks, I hope, Dave Henry (Dan is my Facebook pseudonym) ( DavidJHenry@telus.net )
