i can't contact the dev of this to update the change i made. I renamed the .xpi to .xpi.zip, extracted the install.rdf and edited it in notepad. changed the "7.0" to "40.1.0" and saved it (remember the .rdf not .txt). Then I just drag/dropped the edited install.rdf to the .xpi.zip and renamed back to .xpi. Working as intended on Waterfox 40.1.0.
Still working in firefox 18.*, just changed max version in rdf file.
Try the new restartless alternative
I Love it. Saves many clicks & searching.
This is now part of my Must-Have extensions!
Although the method for making "Open In RegEdit" work with Firefox 4 described by max32x below will work, it will also turn off version checking for ALL other add-ons in Firefox 4. Personally, I'd rather selectively turn off version checking for EACH add-on that doesn't work with the latest version of Firefox so I have some semblance of control. The method I suggested (repeated below), will only allow THIS add-on to work in all versions of Firefox 4.
Simple fix for making "Open In RegEdit" work with Firefox 4.0 and beyond
This has been tested and proven to work with Firefox 4.0 running on Windows XP SP3 32-bit and on Windows 7 SP1 64-bit. This change should allow it to work through Firefox version 5.0.
1. Search for directory (folder) "openinregedit@firefox" (without the quotes). If you find more than one, do the following steps for each one found.
2. Within the "openinregedit@firefox" directory, find file "install.rdf" and open it using Notepad.
3. Change line
4. Close Notepad answering "Yes" to the "Do you want to save the changes?" question.
"Open In RegEdit" will now work properly in Firefox 4.0.
As I have tested it out on my Win7 x64 PC, this add-on can work under Firefox 4.0.1 without the modification described below by Stu Berg. What you only need to do is to force the installation, i.e., to make Firefox 4.0.1 ignore the version incompatibility.
The procedure is as follows:
about:config --> right-click on some empty area to invoke the context menu --> select "New" --> select "Boolean" --> fill in "extensions.checkCompatibility.4.0" (without quotes) for the preference's name --> set the value to false
After doing above, you can add this extension to Firefox without seeing the "...could not be installed..." message.
"Not many people will make use of this extension, but those who do will surely love it."
+10,000! A real timesaver if you're a tweaker, malware fighter, etc...Great add-on.
@all n00b questions that say "Please update to never FF please"
Why you didn't install addons compatibility reporter and you can force use incompatible addons
I liked it when it worked for older versions of FF. Needs an update - please.
When, oh when, is this great addon going to be updated? I have to force compatibility to get it to work with recent FF versions!
All it did was open regedit to the last place it was opened to. I use windows 7 home premium with FF3.6.3.
If you read tutorials on how to tweak your computer often, this Open In RegEdit can save you a lot of time. Not many people will make use of this extension, but those who do will surely love it.
Excellent Add-on. It even allowed me to edit the Registry of a locked pc that has all admin rights removed. =P
A personal favourite that I always install - a must if you are a registry tweaker.
It's working just fine on Vista Ultimate here Skorbion, great little add on thanks.
Outstanding! ... Why has no-one done this before!? Like 'Text Link', it's such a mind-bendingly simple idea, yet so stunningly essential you have to wonder why it wasn't developed sooner! No more copy, hunt through the registry, double click, return to the webpage to copy the value, return to RegEdit to find that the highlight has gone, return to the webpage to find out what the key was again (*sigh*) - Just highlight the value, CTRL+C, right-click, Open In RegEdit, paste. Fantastic!
The '[' and ']' characters often enclose registry keys. For example, when looking at the contents of a ".reg" file. Especially at .
The opening '[' is appropriately ignored by this extension, but the closing ']' appears to break the extension - the last name in the key is ignored.
For example, try this key, both with and without the closing ']' included in the selection:
I would guess that "Microsoft]" is being searched for by the extension, which fails, so the extension just ignores it. The extension should instead ignore just the closing ']'.
As soon as I installed this extension I looked everywhere for the RegEdit tool in Firefox, but I could not find the tool anywhere.
Then I came back to this page and looked it over again.
I selected the key in the example displayed here and right clicked it!
There was the tool!
Remember that you must select a word, right click on it, then select the "Open In RegEdit" tool.
It will open in RegEdit immediately!
This is an awesome tool!
I highly recommend this extension!
This might be best extension since sliced bread
I could really benefit from this add-on, please make it compatible with firefox 3.0. I am unable to install it cause of the version issue.
Aww damn! I made a standalone executable that did this about a year ago, and decided to make a firefox extension to do the same thing and DAMN, you did it... and better. I was in the middle of the extension development when I found your extension.
Radical idea - flawless execution - a perfect 10!
