Diễn đàn hỗ trợ Firefox

I have a user who runs SRS/Crystal Reports on their Windows 11 Lenovo laptop, but every time we go to the website where a Java-enabled pop-up window for viewing spreadsheets is supposed to load we keep getting a "A plugin is required to play this content" error message, but no option to install/approve the running of Javascript.

I have downloaded and installed the JRE and JDK on the endpoint device, but still no luck getting Firefox to load it. I am running the 32-bit version of the web browser, not 64-bit, so I am kind of stumped about how to proceed from here.

Is there a place I can manually download/install these Java plug-ins?

Thanks.

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

I want to have a default download location with the ability to select an alternate location on any download, not to have the last download location remembered as the current save to location.

I have a primary folder to which I want to have the majority of my downloads go to, but on some occasions, I want a download to go to some other location. The current settings "Save files to" and "Always ask you where to save files" do not enable this capability.

Others have asked for this ability too.

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

I recently upgraded my system and, after installing and using Firefox, I notice the Find (Ctrl + F) bar is now at the bottom of the window. Whereas, it was previously at the top (which is more like every other application I use).

After some head scratching and web searches, I remembered I had to fix this issue previously (after a Firefox upgrade some time back). The method to fix it then could be found here: [there a way to put the Find Bar at top] That link is of course to the same question asked 4 years back.

I have once again followed the procedure there explained per: • Access my Firefox profile folder. In my case:

  C:\Users\<Me>\AppData\Roaming\Mozilla\Firefox\Profiles\5ym42ewi.default

• Create folder therein called ‘chrome’ • In that folder create a file called ‘userChrome.css’ • In that file add text:

  .browserContainer > findbar {
    -moz-box-ordinal-group: 0;
  }

However, after doing that (and restarting Firefox), the Find bar stubbornly remains glued to the bottom of the window.

Can anyone tell me how to solve this issue?

As a separate note to the developers: This issue is long-standing, that a web search reveals is still relevant to many users. Any chance of considering making it a standard option?

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Recently Firefox updated. It cleared all of my bookmarks and browser history isn't reloading my last session. I can get the bookmarks from Chrome. The big issue is how do I reintegrate Avast Passwords eol version? Without this I need to use Chrome which isn't my ideal choice.

I use to be able to change firefox icons by adding these files in Firefox under the browser directory

chrome/icons/default/BrowserPreferences.ico chrome/icons/default/CustomizeToolbarWindow.ico chrome/icons/default/default.ico chrome/icons/default/downloadManager.ico chrome/icons/default/main-window.ico chrome/icons/default/openLocation.ico chrome/icons/default/places.ico chrome/icons/default/printPageSetupDialog.ico chrome/icons/default/TabMIxPreferences.ico chrome/icons/default/unknownContentType.ico chrome/icons/default/viewSource.ico chrome/icons/default/Wizard.ico

It worked in version 56 but now in version 97 and this no longer works?

I'm hiding menu items using userChrome.css with option “toolkit.legacyUserProfileCustomizations.stylesheets” set to “true”.

So I am hiding some menu items like for example

1. menu_find { display: none !important }

however though the menu item is gone how do I get rid of the ctrl-F menu shortcut...

I have many such menu items to remove so I need a generic solution to override the short-cut icons associated with the menu items I want to remove

How to allow web page to override a keyboard shortcut. Currently firefox picks up the shortcut instead of the webpage...

For example I have an webpage that detects ctrl-shift-h which worked fine in version 56 but now in version 96 it brings up a "Show All History" dialog

I an doing many such things so I looking for a generic way to override firefox keyboard shortcuts

Not exactly sure when this started, but I recently updated to FF 97.0.1.

I previously made the about:config changes about a year ago when this happened. "Double-click the print.tab_modal.enabled preference to switch between the new experience (true) and the classic experience (false)".

But it's not working now. I even toggled back & forth (false - true - false) but to no avail.

How do I get the Print Preview option showing up in the drop down File menu like it used to be?

I don't know if it is a wrong manipulation or an update feature, but since today when i select a link in the history library, it is now highlighted with big yellow dotted borders instead of the usual subtle black/white single pixel sized dots. How to revert back to the small borders?

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

Before the new update whenever I downloaded a file it would ask where to save the file to every time, now it just asks once then automatically saves any new files I download to the same folder as the previous ones, forcing me to then go to that folder and manually move it to the correct folders. Is there any way to change it back to the right way it was done before they decided to remove our choice? My setting is set to "Always ask you where to save files", with the emphasis on "Always".

After the last update, the PIP overlay button is different and larger because it contains the message "Watch in Picture in Picture" and when hovering the mouse on it makes it bigger because a second more detailed message appears below the first one.

I would like to make the PIP overlay button as small as it was before with no text at all. What do I have to do in order to obtain this effect?

See images. The buttons on video players don't look like play, pause, gear, etc. They look like gamepad buttons. But a gamepad is not connected to my PC and I haven't connected one in months. I have tested it with videos on invidious.snopyta.org and tagesschau.de.

Hello Team,

I have been an avid user of Firefox for as long as I can remember. This however has one major drawback: the accumulation of all the settings and changes over the years! I explain this below.

I have noticed that my browser is not performing as intended, i.e. a lot of browsing especially in pages like Google Maps is very slow, some images and videos are covered by some distorted image, other objects are not loading at all, and the list goes on. Now, I know that most of you will say that this may be because of add-ons. I really wish it was.

I performed the following tests: 1. I created a new profile from about:profiles and loaded it. It was just a bare Firefox with nothing else on it. I was blown away by how everything worked so fast and smoothly. Literally, even Google maps was smoother than it was on Chrome. 2. I started adding my add-ons, etc. Nothing changed, even when they were all added. Everything worked perfectly. 3. I went back to my "broken" Firefox and started changing everything in Settings to match the new profile: especially under Privacy & Security. Still the same issues. 4. Once, on the new Profile, I logged in to sync with my Firefox account so I can pull in my bookmarks, etc. the new profile became "broken" too.

This leaves me with one conclusion. The broken part is deeper in the Firefox settings. Keep in mind that as a long time user of Firefox this is the accumulation of a lot of settings over all these years (including a few changed settings in the about:config page.)

My question now is, how do I reset my about:config changes and anything else related without having to lose my sync? (because if I do and then I re-sync then all those changes come back again.)

Ultimately that is what I think is the solution is: to reset the Settings and about:config settings (and any other related ones) without affecting anything else so that they will be pulled up to the sync server (hence why I need to remain logged into my account) and pushed onto my other Firefox browsers.

Correct me if I am wrong here or if you have any other solutions.
