Diễn đàn hỗ trợ Firefox

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

regards p3ppi

In KDE 5.24.4, Linux. I started to have some issues with "Open containing folder" probably because I installed many Gnome apps which may cause bad configurations in my system.

I suspect this cause this issue even though I don't really have gnome file manager:

https://polywogsys.livejournal.com/309405.html "Gnome based file managers, Nemo/Caja/Nautilus provide the entry org.freedesktop.FileManager1. So it doesn't matter what you set as your default application for the filemanager mimetype - as per the freedesktop.org standard, firefox will always select a filemanager based on dbus (if it's there)"

But because the mimetype points to "dolphin", I dont really have other explanation either: $ xdg-mime query default inode/directory org.kde.dolphin.desktop

There is a specific challenge that i am facing with Firefox and some of the solutions that i have tried is not helping me to resolve the issue.

What's the issue: There are double spaces issue in Firefox

Where is it : 1) Menu 1.1) It's in the Menu New Tab is seen to me as New Tab (more spaces are for demonstration only) 1.2) All the Menu items which have space are show with more then one space including

  1.2.1) File Menu -> New   Window (and all the drop down menus with spaces)
  1.2.2) Edit Menu -> Select     All (and all the drop down menus with spaces)
  1.2.3) View-> Page     Style (and all the drop down menus with spaces)
   1.2.4) All the rest of the menus where ever there is a space there is a double space

2) URL : I type something in the URL and they are double spaced "this is test" will look like "this is test"

   THIS URL looks to be double spaced on firefox https://support.mozilla.org/en-US/questions/1338204?page=2
   like below

3) Numbers in the browser :

   Any number displayed is double spaced in the browser output (most of the times, most of the web pages)
   
   

4) Bookmarks : All bookmarks are double spaced

5) Settings:

Settings: I have tried some suggestions below and they did not work for me.

browser.proton.contextmenus.enabled browser.proton.contextmenus.enabled is still set to false but seems to have no effect toolkit.legacyUserProfileCustomizations.stylesheets=true browser.proton.contextmenus.enabled=false

6) Reference: I have tried some suggestions below and they did not work for me.

When I open https://www.washingtonpost.com/ it loads but after a few seconds it goes blank. This started a few days ago and only happens on firefox.

I have tried the scaling options and it makes no difference. For PDF files, I save them. For webpages, I need to workaround and use Edge or Print Screen and past into a Word document.

I am newly running Windows 10 and reinstalled my printer drivers for HP 4520.

Thank you.

Hello,

When I select text in Firefox the selection is not highlighted. The selection itself does work (e.g. deleting a selected word) but is not visible. The problem occurs in all fields where text can be entered, so the URL space, the search field but also text field on a page like this one. The strange thing is that the problem also occurs in Thunderbird.

I am using Ubuntu 18.04.6 LTS, Firefox 99.0 and Thunderbird 91.8.1

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

I'm a little surprised they've taken away the option of choice when it comes to downloading files. But what's most annoying, is the manager opens u and drops down blocking my view of the page, much less that it makes ms stop and think about what I am about to download.

I do not understand the purpose of this. The old way was safer, cleaner and less annoying. How can, or am I able to get that "choice" back?

When searching for a fix I have seen that that there is/was a similar feature in the Edge browser but it can be undone. I feel Firefox users deserve that option.

Thank you.

Thank you.

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

Since a recent update the spacing of words in Firefox's UI as well as on some websites seems to be wider than normal (instead of a singular space it seems as if each space is now a tab wide). Additionally the numbers have also suffered and are now not presented in a normal font anymore but instead seem bigger and grey instead of white or black. Both of these issues occurred at the same time and appear on the normal User Interface of Firefox (e.g. in the bookmarks or in Firefox's settings and preferences) as well as on some websites/search engines. However when copying the text and numbers from Firefox into a regular text editor everything seems normal and no appearance issues can be noticed. What I've already tried: I've restarted my system multiple times since the issue first occurred. I've removed all contents from /home/user/.mozilla/firefox. I've reinstalled Firefox. I've deleted my cache. I've changed my font preferences in Firefox back to Default(Roboto) after having used Inter before. None of my actions above have changed anything. However, when I log into a different user on my computer and open Firefox there everything seems to be normal, so it seems as if this is a user-specific problem.

Thanks in advance, Emma.

OS: opensuseTumbleweed 20220507 Firefox version: 100.0 (issue has occurred since version 98.0)

After updating Firefox, I now have a horizontal line across the upper portion of my computer screen. I have uninstalled FF and updated again thinking it would remove it. I have searched for a resolution and nothing has worked for me. I don't want to have to pay an expert to remove the line. Please give me a fix for this as it is really bothersome.

I'm sure someone knows how to change pdf icons. I've only been able to change the shortcul icon (which doesn't need changing - microsoft didn't work its evil on it). Please share your expertise!

it happens after upgarde to v.100 every click in the link in thunderbird starts only new empty FF window instead of the link content in a new tab This is not on the thunderbird side, as when I set Chromium as default browser the link is opened correctly.

First, I apoligize if this is not correctly posted here but this kind of fit multiple categories.

I love Firefox and have used it for quite a long time. However, recently I have had multiple issues, most which have not been resolved. This issue however needs to get fixed because I cannot do this every time. For some reason, if I close the browser and open it again, my account has been disconected and it wants me to log in again. I did find a post regarding this from 10 months ago which a user stated the following:

"Your ‘logged-in’ status is stored in special cookies. If the cookie is removed, you are logged out.

You may be in Private Browsing mode or told Firefox not to remember.

Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.

Turn off Always Use Private Browsing Mode Turn on Remember My Browsing And Download History At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off."

I followed this hoping it would be the end of it but it still keeps on happening. If I can't get a solution to this, I will have to use another browser. I hate to think that will happen as no other browser has been as good a fit as Firefox but as I am sure you can imagine, this is getting to be too difficult of a process to do 10-20 times a day.

Thank you for reading and I hope someone has some sort of idea on how I might overcome this annoyance. Stay safe and healthy!

This problem just started today. I am very angry. what is going on with Firefox? Websites are filled to the brim with annoying ad's. and you tube videos are constantly interrupted with ad's!!!!! What is with all the ad's? This problem has not existed until today. Please STOP this! And, No, I can not just wait a few seconds then click on "skip ads" because I am looking at videos on a computer screen while sitting away from the computer in a chair so constantly having to get up, walk to the computer, click on "skip ads", walk back to my chair is an annoyance! Just stop with all the ads!

Sorry for asking a question so many others have asked but I am having trouble completing fixes that were suggested.

I do project research with over 25+ websites and can't do without my p/words especially, but also my bookmarks. I just reset my PC Win 10 and as you know this operation cleans out everything but OEM apps.

So, I downloaded latest ver. FF but my passwords and bookmarks aren't there which I actually anticipated.

I read many posts and replie s on how to restore from old Firefox date filesbut I just don't get it (about:support, Help > troubleshooting information). I located my old FF profile easily. OK fine, now what? Instructions said to copy profile but to where? And how, exactly? Do I paste it somewhere?

Another "Reply" said to locate "Local Directory, no root", then click Paste and restart Firefox. Where is Local Directory? Is there a FF restart button?

Frustrated.

Thanks.

When I modify my website, the updated version shows fine in CHROME and EDGE but shows my old version in Firefox. I cleared browser cache, hit reload numerous times, relogged, all the usual things I could think of.

Have any helpful info?
