A welcome addition to the deficient default find in page function, however, while I choose to highlight all occurrences of a search word (I read the wrench icon page) which can help, yet the search box disappears from view once you click in the page or a word to copy one instance of it.

Nor does it stay in view across tabs, which is an option that many users have requested of Firefox.

Otherwise, if you want to search again for the same word in the page (after clicking on the page ow word) rather than looking for highlights, or you want to search for the same word on another tab then you need to click the icon again.

Using F3 invokes the FF default find in page, which inconsistently sometimes remains in view, if not always keeping the same last search term. A bug has been filed.

All these years and many of us are still waiting for a true replacement of the old FindBar Tweak, though it did not allow Regex.

Note that I have hundreds of tabs open and do much research, and use a desktop, thus not being an average user.

Thank God for such developers as you who help us, Thanks.

I love to hit and type "find " and start searching, it's a breeze

Content of page is deleted when moving from one search result to the next. Repro:
- go to https://www.amazon.com/stores/page/F50AFABA-4CDE-4A95-84D0-CA4C61819FEB/search?ingress=2&terms=tablets
- search with regex: [0-9.]+"
- click the down button 2+ times until the page scrolls
- Expected result: page would scroll or jump, and highlight would be on next result
- What happened: the content between page header and footer mysteriously vanished

The extension looks promising, but this being my first experience, kind of put me off. Look forward to developer followup, after which if the problem clears up I'll review again and revise my review.

Update: I disabled uBlock Origin, the only other extension I had installed. Bug still occurs. I also tried repro with browser Cmd-F, didn't repro. I'll continue trying to use it and report any issues here.

Thanks for making this add-on. This extension deserves a larger audience, has there been any attempt/interest in getting this into the builtin Ctrl+f search?

4 Months after my initial review: Amazing plugin. Thank you Mr. Richardson.

Great regex search plugin. The search function works flawlessly. I deduct one start, as there is no find next/previous keyboard shortcut (at least I don't know of one). Having a shortcut for these two features would be the icing on the cake!

It's good for regex search.

But for some reason, this add-on takes over whenever you use the search bar for anything beginning with 'find'. You can only use it to see how many matches are on the page. Annoying and useless feature.

this is too buggy and slow. use a bookmarklet instaed. make a new bookmark call it whatever you want and add as link: "javascript:(function(){var count=0, text, regexp;text=prompt("Search regexp:", "");if(text==null || text.length==0)return;try{regexp=new RegExp("(" + text +")", "i");}catch(er){alert("Unable to create regular expression using text '"+text+"'.\n\n"+er);return;}function searchWithinNode(node, re){var pos, skip, spannode, middlebit, endbit, middleclone;skip=0;if( node.nodeType==3 ){pos=node.data.search(re);if(pos>=0){spannode=document.createElement("SPAN");spannode.style.backgroundColor="yellow";middlebit=node.splitText(pos);endbit=middlebit.splitText(RegExp.$1.length);middleclone=middlebit.cloneNode(true);spannode.appendChild(middleclone);middlebit.parentNode.replaceChild(spannode,middlebit);++count;skip=1;}}else if( node.nodeType==1 && node.childNodes && node.tagName.toUpperCase()!="SCRIPT" && node.tagName.toUpperCase!="STYLE"){for (var child=0; child < node.childNodes.length; ++child){child=child+searchWithinNode(node.childNodes[child], re);}}return skip;}window.status="Searching for "+regexp+"...";searchWithinNode(document.body, regexp);window.status="Found "+count+" match"+(count==1?"":"es")+" for "+regexp+".";})();" without the first and last ""

It looks a little bit. Search for Search "chor[a-zżźćńółęąś]*\s?ryb" browsing "choroba", "chorobowych"

Sorry, but didn't work for me. After searching, there were never any matches. Turned off regex, tried, but nothing.

Why on Earth this add-on need "Access your data for all websites"? BEWARE. Regex Search does not ask so intrusive information.

Works great! I'm glad i find something like this....

It took me a while to find this add-on and I'm so glad I did. Seems to work well in my short 5 minute testing, i.e. I can search for regular expressions and jump through them using the up/down arrow keys. BTW, I'm not sure what Ckln was saying when he only gave this 2 stars because "On Firefox you can't have a shortcut to make the search pop up that's a shame." I use the default ctrl-shift-f and the search box pops up just fine in my Firefox.

this extension seems to be fine but I have major issues with it:
* On Firefox you can't have a shortcut to make the search pop up that's a shame.
* I'm unable to use built in shortcut as they conflict with my keymap ie Ctrl+Alt+R (on windows) is equivalent to Ctrl+AltGr+R which give me the char ™.
* Also the extention is using the «Access your data for all websites» which give this extention ability to read password and it could use the «Read the text of all open tabs» permission instead.

Is there a way to make this automatically highlight certain values on a particular page every time it loads with 0 input from the user?

It slows the browser A LOT when trying to find anything on a large web page (the most popular use case). It is probably because of "search as you type" functionality. It should be possible to deactivate it. The other possibility is to perform "search as you type" only for expressions longer than e.g. 3 characters. I dislike also a very broad permissions this addon requires. It can be a security concern. Addon named "Multiple Highlight" shows that it is possible to search RegEx without any permission requested.
