Diễn đàn hỗ trợ Firefox

I have Firefox 50.1.0 on openSUSE 13.1 Linux (KDE desktop). This is the last update from openSUSE, but is now deprecated by some websites. I am reluctant to download a recent Firefox version without knowing in advance that it will work under SUSE 13.1. I am familiar with 13.1 and reluctant to update that, merely to run a new version of Firefox, as it will create complications with my multi-boot system, which includes a MSDOS 6 partition for legacy software (it took me ages to get GRUB configured to load that reliably and I'm not sure I could do it again).

Please advise what is the latest version of Firefox that will run under my elderly version of Linux and how to obtain and install it (I am not an expert Linux command line user). I am using Firefox 106.0.3 under Windows 7 to send this to you (multi-boot system), because I could not sign up with 50.1.0.

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

I have been using online banking for years and using Firefox to access my accounts. Suddenly, I now get an error message (see attached) that demands I use another browser (e.g., Chrome, etc.). I want to continue with Firefox. The website support people tell me there is a Firefox update needed, but the latest Firefox is installed. I did the usual and deleted the cache and the site data. No effect.

Can you help?

Laptop: Machine Type: Acer Aspire 5 Laptop (model A515-51-50RR) Processor: Intel Core i5-7200U at 2.50GHz (8GB RAM; 1TB HDD) O/S: 64-bit Ubuntu 18.04 LTS Firefox: 106.0.2 (64-bit)

I use firefox 115.3.1 on debian12 and chat with gpt on poe.com, firefox can't get the response dynamicly and it can only be loaded when the whole response finish, but it run properly whan I use chrome. Whan I press F12, I see many gets were red(ns-error-net-interrupt), how can I fix it?

I'm already using a dark theme and dark color definitions, and whenever I directly view other image files (such as GIF, JPEG, PNG, or WEBP, or even MP4 or WEBM videos), the surrounding background area is a dark gray in accordance with the theme.

However, when I directly view any SVG, the surrounding background area is a bright white instead.  I thought it was pure white but, upon using a color inspector, it's actually #f6f5f4. Strangely, a similar problem happens with Chromium, Chrome, and Edge but the background area with them is actually pure white #ffffff.

I did find the below userChrome.ccs code and tried adding "|svg" to the list of extensions, but this did not change anything.

@-moz-document regexp("((.*\\.(png|apng|jpg|jpeg|gif|tiff|bmp|svg))|(^data:image\\/.*))(\\?([^#]*))?(#(.*))?") { html > body { background-color: #353535 !important; } html > body > img:only-child { background-color:#666 !important; box-shadow: none !important; margin: 0 !important; } }

The SVG's don't have any background color defined.  I tried searching around for "f6f5f4" since that's a pretty specific value, but I guess it's used more than I thought, and I didn't initially find any connections.

How could I adjust this bright white #f6f5f4 to some other color? Thanks

In Firefox Settings (General) there is a section 'applications' that allows you to [[choose an action based on file types|https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file#w_changing-download-actions]]; such as PDF (open in FF, save, etc)

This menu is not functional for me. When I click on the down arrow to change the option, it should open a list - but nothing happens.

I tried rebooting & restarting FF, but the issue remains.

I am using FF 98 on Linux Manjaro.

Normally when I am not using Firefox My cursor is different (I have changed it in settings). Yet when I use Firefox It changes to Ubuntu's Default cursor. I don't know what type of information is required but I will happily provide them if you tell me about them.

So firefox is my favourite browser and I used it a lot. But today, I launched Firefox, opened YouTube and the video had a green overlay. I thought it was in the video but I clicked on an other video: color stripes.

I tried fixing this problem and looked here at this website but everything was for Windows :/

So yeah I hope someone can tell me a solution because I realy don't want to permanently switch to Google Chrome

I'm just trying to NOT have Firefox open my last session when I open it up after rebooting Linux. I've tried many chosen solutions on this site but nothing is working. Here are the settings I've tried with no success (note that I have tried each one individually with a restart between):

"Open previous windows and tabs" is unchecked. "browser.sessionstore.max_resumed_crashes" is 0. "browser.sessionstore.restore_on_demand" is false. "browser.sessionstore.restore_tabs_lazily" is false. "browser.sessionstore.resume_from_crash" is false. "browser.startup.couldRestoreSession.count" is 0 but it sets itself back to 1. "sessionstore-windows-restored" within "sessionCheckpoints.json" in the profile folder is false but sets itself back to true. Deleting "sessionCheckpoints.json" does nothing. I don't have "user.js" in my profile folder.

Here's my system info:

Every time firefox has updated this year it prevents me from signing into my Navy federal credit union account. I get the following error message; Access Denied You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/mfa.fcc" on this server.

Reference #18.82b3417.1697332724.50b30aec

I have had to turn off the ad blockers in the past and delete all the history including sign ins to get it to work again. This update I again went through all of that and also tried turning off every extension, turning off firefox tracking blocker and even reset the network setting to no proxy. Nothing works. Will I have to go back to using the google spyware browser just so I can do my banking? Or can this problem finally be fixed? If firefox worked with NFCU forten years prior without any difficulty I don't know why it cant be fixed.

I have today commissioned a new HP laptop running Windows 10.

I have downloaded Firefox and done a straightforward installation. I have viewed a couple of web pages but notice that when right clicking there is no longer a screenshot facility in the little menu box that appears. Trying Control + Shift + S does not work either.

I am writing this using Firefox 93.0 for Linux Mint on an old Toshiba Satellite and I have the facility - both right click and keyboard.

Has the facility been discontinued in the later version?

Many thanks in advance

I ASK AGAIN: WHY ARE THERE SO MANY USELESS GADGETS ON IGHOME PAGE?

THERE IS AN "ADD GADGETS" LINK THAT GIVES HUNDREDS OF BLANK AND USELESS LINKS.

WHY NOT ELIMINATE THEM ?

I am setting up a homepage called bento and every time I open the page it shows "Allow this local file to access your location?" with no "always allow" function. Anyone got any ideas?

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

Hello,

Recently, I updated ubuntu to the latest version, and had set Firefox as my primary browser (as I normally did).

I, however, could no longer access to the local hidden directories, i.e.: .local, etc., with this version. I even tried to disable Firefox sandbox security, security.sandbox.content.level = 0, and changed chown/chmod to the lowest levels, but those didn't help.

The issue can be repeated via the URL in Firefox as followed:

file:///home/y2021x/.local

or any other hidden directory. I could open these files/directories in the older versions of Firefox.

Am I overlooking something? I appreciate very much if you could help me find out the solution to this problem. Thank you very much.

Same as question 1337885, which was marked "solved", despite never being solved. (Solved for a few months is not solved!)

Does every user seriously have to go through the rigmarole of manually editing a CSS file in order to have a usable UI? (as per https://ourtechroom.com/tech/get-back-old-tab-design-firefox/, for example)

When I right click, the contextual menu opens where the mouse is and what is under the mouse is automatically selected and executed, closing immediately the contextual menu and doing something I didn't asked for. How to not get that?

This question is asked too here https://forum.kde.org/posting.php?mode=post&f=304
