Diễn đàn hỗ trợ Firefox

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

When using the new version of Firefox, I found that bookmarks only appeared in new tabs. Once I opened other web pages, there were no bookmarks above the screen, which made me feel inconvenient. Previously, the new tabs could also be customized, but now they can only be blank or the default pages of Firefox. So, can the new version of Firefox solve these problems? Or which of the older versions of Firefox can still meet my requirements?

Hello,

I can't figure out how to add a custom search shortcut, is this no longer possible in Firefox (without installing addons/extensions)?

I recall 'custom search' being more or less ubiquitous, and feel like there was an "Add" button below the Search Shortcuts UI not that long ago.

Bookmarks with keywords would be a reasonable workaround if it weren't for having to prefix the keyword to the search terms.

Thank you, Kyle

Okay, i have been using librewolf for awhile now since i got my desktop fully built. today i went to go search something related to my phone and instead of using duckduckgo it automatically used Google. i do not want this and have no idea how to fix it

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

been having issues with files lately. i can dl a file and open the folder. if i try to open the file from the browser or the folder directly, the browser window will freeze. additional browser windows are still functional. how do i fix this? no files will open even in safe mode.

In Chrome, for example, if you type "maps" in the address bar, it will autofill to "maps.google.com", which then redirects to the correct URL, "google.com/maps". Initially, it doesn’t do this, but if you do it repeatedly, Chrome eventually learns and sends you directly to that URL when you type "maps". The same happens with "gmail" or even just "gm", which redirect to "gmail.com" or "mail.google.com". Does Firefox have this kind of feature?

I think I browsed a reddit thread from a few years ago asking this same problem having something to do with autofill frequency which doesn't work, because the actual url is not, in the example of maps, maps.google.com and the url I want to enter redirects to it.

When navigating through video websites, the browser often becomes unresponsive and refreshes the interface. When accessing other websites, the browser tabs frequently experience crashes.

Details regarding the operating system, laptop model, and browser version are provided below, and the screenshot of unresponsive website has been attached with this, um email or message.

Hello, after a power cut I lost all my bookmarks. When I try "Manage Bookmarks -> Import and Backup -> Restore -> Choose File..." nothing happens.

In the folder ".mozilla/firefox/6924v31j.default-1728390329118/bookmarkbackups" there are several backup files, but the newest has the date Jun 25, though the name suggests it's from Jul 2: -rw-r--r-- 23850 Jun 25 13:07 'bookmarks-2025-07-02_184_mg1znof1NbBiyJ14ZcO9SluvTvLZI-rxPSm20YZUJww=.jsonlz4'

In the directory ".mozilla/firefox/6924v31j.default-1728390329118" there is also places.sqlite from Jul 4 11:59 (that was the moment when the power was cut).

How can I restore my bookmarks?

Firefox has shortcuts at the top of any new tab opened. These are usually your most visited pages. For most shortcuts, if you click the three dots you get a menu of: Pin Edit Open in a New Window Open in a New Private Window Dismiss Delete From History

This is the menu you get for almost all shortcuts EXCEPT for Amazon. For the Amazon shortcut you get: Pin Dismiss

That's it. No opportunity to edit it. And if you click on the shortcut, it doesn't take you to Amazon.com, instead it opens "Amazon.com Search" in the address bar. I don't want Search, I want to go to the Amazon home page but the shortcut doesn't take me to the Amazon homepage like it used to. Why is this broken now?

When opening Firefox, the screen turns white before page opens! There is a version that was updated for this issue however,at that time I did not have this issue! After downloading the newer version, I now have this white light issue! I like to mention, my computer never crashed! I believe (134.0.3), was the update that was a fix for the White Screen problem. And, I am using ver-139.0.4 (64 bit) (win. 10-64 bit) I appreciate any help with this issue! Thank you!!! geo (7/6/2025)
