Diễn đàn hỗ trợ Firefox

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj

How to do

Fix it so the FireFox browser Version 88.0 for Ubuntu (Linux) works AGAIN at saving website Login data using a Primary password via your 'FireFox Sync' advertisement (documentation).

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

Up until Firefox 64, Firefox had limited support for RSS:

• Viewing a RSS feed would show you the feed items, with an option to do something with the feed.
• Live bookmarks would actually subscribe to those feeds

I can understand removing Live Bookmarks. It's a big feature. I don't understand removing the (what I assume to be) XSLT stylesheet that made RSS feeds not look like a wall of XML. Does anybody know what the conversation was here? Are there minutes?

Even basic RSS support helps people interact with the web, and since Chrome and Firefox both dumped RSS, users are being driven further and further into the arms of "Platforms" who handle this stuff through black-box algorithms. And so much tracking.

Mozilla should reverse this one. Bring RSS back hard.

On this page with an Atari emulator, I am unable to use its controls that use the Alt key, such as Alt+P to pause.

It works with another browser, or with a fresh profile.

I've tried disabling add-ons and trying it again, but it fails even after disabling each of them. It also doesn't even work in troubleshooting mode, and that seems kinda odd?

It may be some modified settings in my Firefox profile? Though if it is, I don't know what settings, nor how to fix it. What sorts of settings are retained even in troubleshooting mode?

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

Hi, Could someone tells me how to deactivate the startup popup upon each firefox start which says (translated) "thanks this is 100th version of firefox, start navigation", or is it to stay until the 1000th annniversary ? Thanks

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

Got sick and tired of having to enter payment card info every time, so I decided to RTFM and follow instructions. I worked my way thru all the instructions on found on the forum pages, and was entering the information via about:config, and got to the popup where I was asked to confirm, and clicked the button, then clicked it harder, but nothing happened.

My guess is that my Firefox and/or my Leap15.3 installation has left some file permission read-only and Firefox is unable to save this bit of data, but I really don't want to run Firefox as root. I can say more, but I see there are more boxes to fill.

So, I included a screenshot of what I hope will be the useful part of my config file.

I would like to enable picture-in-picture without constantly having a popup for it anytime my cursor goes onto the video screen. You could just put a button somewhere out of the way. It's so annoying I have to just disable it, and that's not right. Nobody needs popups of any kind for anything ever. It's the same as an ad.

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Thanks!

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Find out why and fix issue with pages not loading. Get a white blank page after a search inquiry on some web sites, (lowes.com),

I cannot install English GB dictionary for my spell checker. When I click add dictionaries it takes me to a page where I can select Englsih GB as one of the dictionaries available in my locale. It then takes me to the info and remove page for the dictionary but there is no option to install and no pop up to start the download appears.

To post on this support forum I just created a Firefox account. The system then emailed me a verification code to check my address. While nearly the entire email was in English, the time seemed to be rendered in Greek. This seems a bit odd to me. My browser is set to English, with no other languages present. My IP address is in the Netherlands. See the contents of the email below.

Cheers, Maarten

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

Since about a month, the download dialog pops up multiple times a day (seems randomly; I did not download anything manually). If the list of downloaded files (history in download dialog) is not empty, it pops up and stays. If the list of downloaded files is empty, it also pops up randomly and immediately disappears again.

I searched for this issue and found out that the automatically popping up download dialog can be disabled with `browser.download.alwaysOpenPanel=false`. Unfortunately, this is not what I want because the dialog should pop up when a download has been completed - but not randomly.

I would like to find out why this happens because I am a bit afraid that this may be malicious behavior (e.g., triggered by an extension). Do you have any idea where this behavior comes from or how to figure this out? Are there appropriate logs to take a look at? Can I see somehow which Firefox components are active at which point in time?

Edit: Just found other users with the same issue (but no solution, yet): - https://support.mozilla.org/en-US/questions/1370262#answer-1492291 - https://support.mozilla.org/en-US/questions/1370262#answer-1495496

Could you add a option of closing tab with <kbd>Ctrl</kbd>+<kbd>w</kbd> to the advanced preference?

Also, I realized that:

```browser.tabs.warnOnClose False``` Does this option activates warn when closing the tab? If your answer is yes, it is not working at all.

Hi,

I use Mendeley Web Extension to pull articles and other things from Firefox directly into my Mendeley library. I will usually rapidly read through the PDF file online before deciding to add it or not. For some unknown reason, Firefox blocks the use of Mendeley on PDF file, for security reasons, and I can no longer add them to my library. Most references are only available as PDF files making the add-on completely useless. Is there a security feature that I can disable to be able to use the extension again?

Kind regards,

Mathias
