Diễn đàn hỗ trợ Firefox

For the past few months I've been starting to have some trouble with other sites that I go onto. For example, on Google if I try to search something that has 'a' in it, it ignores the rest of my query and searches up everything leading up to the A. Even just pressing A it's almost like it's acting as a mouse-click, but this problem only seems to be occurring on Firefox, nothing else.

What's going on?

Is there a way to fully edit a .pdf file in the new Firefox browser? I know how to annotate, but I don't see any way to copy and/or paste. This originally came up when I wanted to copy one sentence from of an entire document. Thank you.

Hi, I don't know why, but my firefox's console suddenly started highlight dom elements only with borders, without background colors for padding and margin as usual. How to get them back? Attaching 2 images: one from firefox, with current boder-highlights, and sadly one from chrome, because firefox doesn't have anymore, with background highlights, just as an example of how, circa, was FF before.

How to get back?

Firefox 112 update will not download completely. It just keeps saying it is downloading but it does not complete. I can't access some websites now since I have been trying to download the update. Please help. Thanks.

In short, "Open previous windows and tabs" is no longer working. I'm using version 111.0 (64-bit).

I have done the following: 1. Troubleshooting mode 2. Removed or disabled all my extensions 3. Refresh Firefox - twice! 4. Disconnect sync across my two laptops

Still, nothing is fixing the issue. My previous windows and tabs are not being restored.

Help, please!

I have had several computers and a phone synced with Firefox. Recently, my mac book had to be wiped and OS reinstalled. Since then I have been unable to sync to my Firefox account on that laptop. I enter my standard email and the same password as on my desktop, but get an error stating, "Incorrect Password".

Following suggestion from an older thread with the same problem, I installed a nightly build on my desktop and tried to log in with that, unsuccessfully. Same problem. I used my same email and same password, but the nightly build version of Firefox reported the error, "Incorrect Password".

While thinking about this, I checked my newish phone and found it was not synced either. Using my email and password, I was unable to get it to sync. However, I was able to sync the phone using the QR code. So my phone is now synced to my Firefox account.

I really want to get the laptop to sync to my Firefox account and am mystified as to how to track down what the problem might be.

It works on librewolf and brave, and im running on fedora 37 (using the flatpak package) i have tried every fix including but not limited to: reinstalling, troubleshoot mode, making a new profile and clearing cache. also the openh264 plugin always says preparing to install or smth but never does, thought id mention it in case its important.

I have an on-line subscription to the Sydney Morning Herald. Recently, every time I try to read an article, Firefox freezes. I can read SMH okay on my iPad. If I transfer the SMH Article URL into Edge everything works okay. What have they done to Firefox?

I noticed this first when I had to force Google to go into dark mode even though firefox was already in dark mode.

I have searched through some issue reports and have seen a lot of people mentioning that their system theme is not being detected properly. This is not that issue. I can set the firefox "Website appearance" to dark or automatic at which point the UI of firefox itself does do into dark mode so no issues there. However if I go to a website that tries to query 'prefers-color-scheme' and set its theme accordingly it always returns 'light'. This is the case even if I set the 'layout.css.prefers-color-scheme.content-override' to 0 in about:config.

I used this website to test: https://septatrix.github.io/prefers-color-scheme-test/

The issue persists when opening a website in a private window.

Let me know if I need to provide additional information.

Hi, I disabled several options in About:Config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and moved to it automatically. Whatever you do with the current tag, I want it. Please help me. ( I mean, it no longer applies to bookmarks, I want it to apply to bookmarks )

When I open "Extensions" (about:addons) by clicking the Extensions icon, I want it to start on my own extensions, not Recommendations. How can I make "Extensions" open to the actual Extensions tab? Or can I remove the "Recommendations" tab entirely?

I already saw [to remove 'Recommendations' tab in about:addons]. But about:config

 extensions.htmlaboutaddons.recommendations.enabled = false

only removes recommendations from the Extensions tab. And adding

 extensions.getAddons.showPane = false

does not work, the Recommendations tab is still there.

Hello,

When I try to log in to tradestation.com, I get a 403 Forbidden message. I have gone to Settings - Clear all History, and checked all the History and Data boxes, and clicked OK. Also, I only use Private browsing, which is set to remove all history, caches, etc. whenever I close Firefox. I have been logging in to tradestation 4 or 5 days a week for months, until today. Please help fix this.

Thank you, Barry

A few days ago, I tried to log in to yahoo mail, and started getting this after I clicked okay: "Redirecting . . ." (print screen below). Now I get the same problem when I paste links into the search bar. I think this started with the new March 31st update. It isn't just one site or application, which seems to suggest that FF is the problem. https://prnt.sc/dIc_AerJtR7g The tab gets stuck there.I cannot view my mail on ff at all, but I can on my phone, probably because I wasn't forced to log out and back in. I cannot paste links. FF is basically unusable for me right now except for sites that I use frequently.

Hello. I un-installed Microsoft Edge and Office 365 and now Firefox has stopped working (on another computer not this one).

This is the same problem that someone reported in 2021, but that thread has been archived.

https://support.mozilla.org/bm/questions/1356550

The advice then was to re-install Firefox and to download Visual C++ \ Visual Studio files ( especially VCRuntime1401.dll).

My problem is that I don't have a browser on that computer, I am completely cut off from the internet and can't download anything.

Is it possible to download the necessary files on this computer and transfer them to the one that has the problem? Thanks.

Same as this question, but the answer is outdated: https://support.mozilla.org/en-US/questions/839240

Is there a way to do this in the about:config page?

There is an answer about holding `Alt`, but that is a workaround.

Firefox always brings up the saved password for a particular website, but the password is old and wrong. Going to the Logins and Passwords management page, I enter a search for the website as it appears in the address bar, but there is no associated login in Firefox. There is no password associated with any part of the website's name or URL in 'about:logins' . Yet still some password shows up with a saved login. How do I find the password for this website and correct the password?

Hello people,

Lately, I've been having the problem with bookmars.

When I want to save my favourite pages to specific folders I created for different areas, I always used the method where you click in panel with www address e.g. https://support.mozilla.org/, the whole address is now selected and I drag that addres to specific folder of mine. When placed, the bookmark was saved to that folder, but in addition to that, Mozila browser also fetched bookmark title with title of the page.

So after drag-and-dropping the link https://support.mozilla.org/ I ended up with bookmark in my folder, that looked like this: "Get Support | Mozilla Support"

Now when I do the same procedure, I just copy the link addres itself. So it ends up like this: "https://support.mozilla.org"

You get the idea. )Where did the feature of fetching titles dissapear? Can it be returned back?

I've been using bookmarks this way (drag-and-drop by mouse to specific folder) since I can remember. And this problem occured just week ago. It helps me to speed up my process faster than using the star icon. And now I dont even know what I saved when I look at my folder and try to make sence of it the next day, because everything I can see is link addresses.

I tried it on many computers and many diferent systems Win10 11 etc and I still get the same problem. I tried it with reinstalling Firefox, with deafult settings, in normal or inkognito mode. Nothing works.

Any help? Can this be fixed?

Best regars, J

Recenltly bought new laptop and installed a new version of firefox, but now I cannot get it to show my extensions.

The screen shot shows what (IMO) is supposed to to be, but all I get is the default buttons for firefox 2nd picture

Expected: Firefox displaying all known Unicode characters.

Result: Many characters missing.

Failure page as an example: https://en.wikipedia.org/wiki/Religious_and_political_symbols_in_Unicode

Description: I tried going through a Unicode list Unicode list and the extensive set of characters displayed correctly. However, when reaching further into character sets as shown in the failure page page, many are missing which are not new.

• "Repair encoding. . ." button was not active.
• An encoding switch extension was not able to resolve the issue.
• Troubleshooting mode did not show changes.
• Switched fronts available such as Noto Sans and Roboto Sans without success. Possibly a font failure?
