v2.2.3 has problems with "Animate tab" option. Ubuntu 18.04 LTS, Firefox 63.0 x64. When "Animate tab" animates - it causes some memory leaks or read/writes on HDD, so my PC will operate slower and slower and then it will completely frozen, and the only ways to avoid this - to click on monitored tab to stop favicon animationon, or to disable "Animate tab" option at all! Something became unstable with the last FF version.

Didn't notify me of change with a sound or blinking tab.... the tab was just blank without favicon and it had stopped refreshing and then when I manually refreshed I saw the changes on-site. I was at my computer when changes happened, browser was running, volume was up..... so yeah, glad I didn't pay to get email updates because I'd be sorely disappointed. Firefox 62.0.3

Please put STOP/START button on top of the dialog box or by click or right click on icon and ALSO to set by default the keyword so that we do not have to select text (regex) everytime we click START.

Doesn't work at all - I click the icon and nothing happens.

Firefox 62 64 bit Linux, private mode.

Sadly, entirely nonfunctional. No context menu, no nothing on Ffx Quantum 61.0.2 64-bit

I was using this to check for a test date cancellation to open up at a testing center that is booked up until January. I thought I was going to have to sit at my computer non-stop for days checking and competing with many other students to find an opening. I installed C4C not knowing if it would help or not. Within 45 minutes the song played to notify me and I thought it was a mistake. Nope, grabbed a test spot in 2 weeks, it was unreal. I still can't believe it happened.

Saving custom settings renders the addon useless.

Mit Version 2.2.2. haben sich Fehler eingeschlichen (z.B. wird das Audio-File nicht mehr in Schleife gespielt - sehr ärgerlich!). Entwickler gibt leider keine Rückmeldung. Ansonsten funktioniert das Addon. Keine Fehlerbehebung in Version 2.2.3.

Version 2.2.2 introduced some annoying bugs, such as the manually selected audio file that cannot play in a loop anymore. The developer ignored my request. Otherwise the add-on is fine. No bug fixes in version 2.2.3.

welllllllllllllllll

Need the log to file functionality.

Love it! works great on laptop...gave it 4 stars because it does not work on Firefox for Android. Can the developer confirm that he knows this and is working on it?

Great extension, but it's missing random interval refresh so I can put refresh interval like between 10-15 seconds or 20-30 etc...

Check4Change was working better with audio on Firefox 57 but on Firefox 59.0.2. it's not been working properly. No audio to call attention to any change and looks like it's delayed on Firefox 59,0.2. Can you please help resolve this?

Doesn't work for sites that take 1-2 seconds to load some elements. I wanted it to check if a parcel had arrived, by checking on changes to the tracking page. Didn't work.

It's super intuitive and just the thing I was looking for. Makes my work remarkably easier. Also, very pleasant tune.
